飞艇载无源雷达的外辐射源选择

摘要

As a special form of bistatic radar,passive radar based on external transmitters uses different commercial illuminators as its signal sources.It has become a research hot topic for its strong battlefield sur-vivability.The paper illustrates the detection theory of passive radar based on external transmitters,and fea-sibility analysis for various illuminators is disscussed.Then detection range and detection coverage of various signals are calculated.The conclusion is reached by means of comparing detection performance of different illuminators.The conclusion provide some theoretical reference for further research on stratospheric airship-borne passive radar.%外辐射源雷达系统是双基地雷达的一种特殊形式，使用各类商业信号作为信号源，具有较强的生存能力，已成为当前雷达探测领域的研究热点。以平流层飞艇为运载平台，首先从理论上分析了该体制雷达的探测原理，对现有的外辐射源进行了可行性分析，计算了在各辐射源条件下该系统探测距离和观察面积，通过对不同辐射源探测性能的对比给出相应结论，为进一步分析该体制雷达的探测性能提供了一定的理论参考。
