摘要
针对静默哨兵系统等隐身雷达的战场机动能力不足,提出了一种便携式无源侦察系统的设计方法。通过三点布站对目标测距定位,对信号作相关处理,提高侦测距离,用时域遍历代替相控天线在空域遍历实现多目标功能。计算结果表明,最大侦测距离可达70 km,最多可同时探测20个目标。方法简洁,造价低廉,对构建国土和城市重点防御有一定参考价值。
Aiming at the fault of silent sentry radar system in war field,a kind of method based on portable passive radar is introduced.Target can be ranged by triangle-locating method.The detection range is increased by coherent processing of the reflected signals.The multi-target detection can be realized by time delay match-scanning in time domain,instead of space-scanning by antenna array.The calculated results show that the detected range can be 70 km and the radar can detect 20 objects at the same time.This method is valuable to the emphasized recovery systems of countries and cities due to its simplicity and low cost.
