無源雷達在非軍事用途的應用日益廣泛,這是其最有前景的前景之一。由於被動雷達不像傳統的主動雷達那樣發射訊號,因此非常適合電磁污染和頻譜許可問題嚴重的都市區。被動雷達可以幫助空中交通管制、機場周邊安全、都市區無人機監控和關鍵基礎設施保護等民用產業提高安全性和感知能力,同時又不會干擾其他電子系統。此外,隨著無人機、空中計程車和自動配送系統的普及,城市需要低成本、可靠且低排放的監控工具。
先進主動雷達系統帶來的威脅
儘管被動雷達具有明顯的優勢,但得益於自適應波形設計、數位波束成形、氮化鎵 (GaN) 放大器和主動電子掃描陣列 (AESA) 架構的進步,有源雷達技術仍在快速發展。這些進步在探測範圍、解析度和目標追蹤精度方面顯著超越了現有被動雷達系統的可靠性。這些高性能有源系統因其久經考驗的效用、靈活性以及在戰場上更直接的控制能力,經常受到政府和軍隊的青睞。在部署和投資方面,無源雷達可能會被淘汰出這場技術競賽,尤其是在被動系統無法匹敵或與現代雷達性能整合的情況下。
新冠疫情對無源雷達市場產生了多重影響。一方面,全球供應鏈中斷以及醫療保健預算的重新分配導致國防採購和研發活動暫時停滯,導致多項無源雷達開發和部署計畫被推遲。旅行限制和封鎖也影響了現場測試、系統整合和關鍵零件的製造。然而,疫情也凸顯了低排放、非侵入式監測技術在無人空域、邊境和禁區監測中的價值,重新激發了人們對軍事和商業應用被動雷達系統的興趣。
預計被動連貫定位(PCL)領域在預測期內將佔據最大佔有率
預計無源連貫定位 (PCL) 領域將在預測期內佔據最大的市場佔有率。透過利用現有的非合作發送器,例如FM廣播、電視廣播和行動電話訊號,PCL 系統無需發射雷達訊號即可探測和追蹤目標,從而具有極高的成本效益和隱身性。 PCL 系統在現代戰爭和空域監控中特別有用,因為它們適用於城市環境並能抵禦電子對抗。此外,隨著各國優先考慮低排放監控系統以降低探測風險和營運成本,PCL 系統的使用率正在上升,鞏固了其市場領先地位。
預計預測期內,太空領域將以最高複合年成長率成長
預計太空領域將在預測期內呈現最高成長率。太空情境察覺和星基監測支出的增加,以及對不依賴地面基礎設施的全球覆蓋的戰略需求,是這項快速擴張的主要驅動力。天基被動雷達系統正在利用來自地球或其他衛星源的機會訊號,提高其對軌道或空中物體進行高度隱身追蹤的能力。這些系統對於尋求在保持隱身能力的同時保持軌道域感知和高層大氣感知的國防部隊至關重要。此外,衛星星系和小規模空間技術的發展進一步推動了天基被動雷達解決方案的使用和可擴展性。
預計歐洲將在預測期內佔據最大的市場佔有率。這得歸功於其對尖端國防技術的大量投資、對電子戰能力的日益重視以及被動雷達系統主要開發商的存在。由於被動雷達系統價格低廉且隱身性能好,歐洲國家正積極將其應用於城市安全、防空和邊境監控。此外,歐盟致力於提高情境察覺並減少對主動雷達系統的依賴,這也推動了該地區的需求。國防部與私人企業之間的合作使歐洲在全球無源雷達市場主導地位,德國、英國和法國等國家是採用無源雷達的主要國家。
預計亞太地區在預測期內的複合年成長率最高。這歸因於地緣政治緊張局勢加劇、國防預算增加以及韓國、日本、中國和印度等國家對先進監測技術的需求。由於該地區致力於提高低排放探測能力以保護其海洋、領空和邊境,被動雷達系統的應用正變得越來越廣泛。持續的軍事現代化計劃、快速的技術進步以及國內國防製造業投資的增加,市場正在成長。此外,隨著各國尋求更具彈性和隱身性的雷達解決方案來應對現代威脅,亞太地區正成為無源雷達部署和創新的熱點。
According to Stratistics MRC, the Global Passive Radar Market is accounted for $1.67 billion in 2025 and is expected to reach $3.58 billion by 2032 growing at a CAGR of 11.5% during the forecast period. Passive radar is a type of radar system that detects and tracks objects by processing reflections from non-cooperative sources of illumination, such as commercial broadcast signals (TV, radio), cellular signals, or other ambient electromagnetic emissions. Passive radar is more covert and less vulnerable to jamming or detection than traditional active radar because it doesn't emit its own signal. Both military and civilian applications can benefit from this technology, which lowers the possibility of interference or interception while improving situational awareness. Moreover, sophisticated signal processing methods are used by passive radar systems to separate target information from clutter and background noise.
According to the NATO Science and Technology Organization (STO), passive radar systems-especially when fused with active radar-significantly enhance detection reliability across ground, sea, and air platforms. In a 2019 trial involving seven NATO nations plus Australia, Sweden, and Switzerland, the fusion of active and passive radars was successfully demonstrated in a mobile military network
Growing interest in secret monitoring
The ability of passive radar systems to conduct surveillance without actively sending out signals has led to their increasing adoption. Because enemy forces cannot readily detect or target them with anti-radiation weapons, they are perfect for covert missions. Tracking low-observable targets like drones or stealth aircraft, passive radar offers a covert and secure way to monitor airspace in military and defense scenarios, particularly in contested and hostile environments. Because passive radar can function covertly and improve the resilience of detection infrastructure, NATO has highlighted the significance of such systems in contemporary air defense architectures in its research programs.
Complex requirements for signal processing
Passive radar must use signals that are not intended for radar use, in contrast to active radar systems that can modify the transmitted waveform to meet particular detection objectives. This leads to significant difficulties in target discrimination, Doppler processing, clutter removal, and signal synchronization. The receiver must contend with signal multipath, delays, and interference from the original broadcaster while gleaning valuable reflections from a noisy environment. Therefore, sophisticated real-time signal processing algorithms, high-performance computing power, and expert system calibration are needed for passive radar systems. System complexity, development expenses, and maintenance burdens are increased by these technical requirements, particularly for civilian users or new entrants lacking defense-grade experience.
Growth in the commercial and civilian sectors
The growing ability of passive radar to be used for non-military purposes is one of its most promising prospects. Passive radar is perfect for urban areas where electromagnetic pollution and spectrum licensing are issues because it doesn't emit any signals like traditional active radar does. By using passive radar, civilian industries like air traffic control, airport perimeter security, urban drone monitoring, and critical infrastructure protection can increase safety and awareness without interfering with other electronic systems. Moreover, cities will need low-cost, dependable, low-emission surveillance tools as drones, air taxis, and autonomous delivery systems proliferate; passive radar technology is well-suited to this role.
Threat posed by sophisticated active radar systems
Despite the distinct benefits of passive radar, active radar technology is still developing quickly owing to advancements in adaptive waveform design, digital beamforming, gallium nitride (GaN) amplifiers, and AESA (Active Electronically Scanned Array) architectures. These advancements are significantly exceeding the dependability of existing passive radar systems in terms of detection range, resolution, and target tracking accuracy. These high-performance active systems are frequently preferred by governments and militaries due to their demonstrated battlefield utility, flexibility, and more direct control. In terms of deployment and investment, passive radar may be eclipsed by this technological race, particularly if passive systems are unable to compete with or integrate with contemporary radar capabilities.
The COVID-19 pandemic affected the passive radar market in a variety of ways. On the one hand, defense procurement and research and development activities were momentarily slowed down by global supply chain disruptions and budget reallocations toward healthcare, which caused several passive radar development and deployment programs to be delayed. Travel limitations and lockdowns also had an impact on field testing, system integration, and the manufacturing of critical components. However, the pandemic highlighted the value of low-emission, non-intrusive surveillance technologies for unmanned airspace, border, and restricted zone monitoring, which sparked a resurgence of interest in passive radar systems for both military and commercial uses.
The passive coherent location (PCL) segment is expected to be the largest during the forecast period
The passive coherent location (PCL) segment is expected to account for the largest market share during the forecast period. The ability to detect and track targets without releasing any radar signals-making it extremely cost-effective and stealthy-by utilizing existing non-cooperative transmitters, such as FM radio, TV broadcasts, and cellular signals, drives its dominance. Because PCL systems are compatible with urban environments and resistant to electronic countermeasures, they are especially useful in contemporary warfare and airspace surveillance. Moreover, the use of PCL systems keeps growing, solidifying their market-leading position as countries prioritize low-emission surveillance systems to lower detection risk and operating costs.
The space-based segment is expected to have the highest CAGR during the forecast period
Over the forecast period, the space-based segment is predicted to witness the highest growth rate. Growing expenditures in space situational awareness, satellite-based surveillance, and the strategic requirement for worldwide coverage independent of terrestrial infrastructure are the main drivers of this quick expansion. Through the use of opportunity signals from Earth-based or other satellite sources, space-based passive radar systems provide improved capabilities for highly stealthy tracking of objects in orbit or in the air. For defense forces looking to stay covert while maintaining orbital domain awareness and upper-atmosphere awareness, these systems are essential. Additionally, the use and scalability of space-based passive radar solutions are further accelerated by the development of satellite constellations and smaller space technologies.
During the forecast period, the Europe region is expected to hold the largest market share, driven by significant investments in cutting-edge defense technologies, a growing emphasis on electronic warfare capabilities, and the presence of important developers of passive radar systems. Passive radar systems are being actively adopted by European countries for urban security, air defense, and border surveillance because of their affordability and stealth. Furthermore, the European Union's efforts to improve situational awareness and lessen reliance on active radar systems have also increased demand in the region. With the help of partnerships between defense ministries and private sector entities, nations like Germany, the UK, and France are among the top adopters, securing Europe's leading position in the global passive radar market.
Over the forecast period, the Asia Pacific region is anticipated to exhibit the highest CAGR, driven by growing geopolitical tensions, increased defense budgets, and the need for sophisticated surveillance technologies in nations like South Korea, Japan, China, and India. Passive radar systems have become more widely used as a result of the region's emphasis on improving low-emission detection capabilities to protect maritime areas, airspace, and borders. The market is growing as a result of continued military modernization initiatives, rapid technological advancements, and higher investments in domestic defense manufacturing. Moreover, Asia-Pacific is becoming a hotspot for passive radar deployment and innovation as countries look for more resilient and stealthy radar solutions to combat contemporary threats.
