分布式无源雷达系统由于具有隐蔽性、反隐身等优势,将广泛应用于空天地海雷达组网探测领域中。文中针对分布式组网远场、近场两种应用场景,设计了非相参、相参后检测以及联合相参处理的检测器,并详细推导了相应检测器的检测概率与虚警概率数值表达式,与仿真相结合验证了检测性能。该研究为分布式无源远场雷达目标测角与近场雷达目标定位应用提供了探测方法理论支撑。

The distributed passive radar system will be widely used in the field of network detection of air, earth and sea network radar systems due to its advantages of concealment and anti-stealth. The detection design of non-coherent processing, coherent processing before detection and joint coherent processing and detection are designed for the two application scenarios of short baseline and long baseline in distributed network. In addition, the numerical expressions of detection probability and false alarm probability of the corresponding detectors are derived in detail, which verifies the detection performance combined with simulations. This paper provides the theoretical support of detection methods for the application of target angle estimation of distributed passive short baseline radar and target location of long baseline radar.
