某型雷达侦察设备动态范围测试方法优化探讨

Optimization Discussion of Dynamic Range Test Method Based on a Certain Type of Radar Reconnaissance Equipment

论文基于某型雷达侦察设备的系统灵敏度和动态范围的基本测试方法,提出了一种优化测试方案,进一步考虑了实际信号辐射到达测频前端和测向前端的功率情况,通过使用均衡器匹配方法,弥补了测频和测向前端的通道增益差异,较好地解决了该通道匹配问题。通过优化方案的模拟测试与指标转化结果,可以验证该优化方案更能等效代替大功率辐射源辐射法测试,为以后的整机系统调试、测试以及产品检验提供优化思路。

A kind of optimization test method in this paper is proposed based on the test method of system sensitivity and dynamic range with are radar reconnaissance equipments .The actual signal power that arrives at frequency measurement front‐end and direction finding front‐end are further considered .The channel matching problem between frequency measure‐ment front‐end and direction finding front‐end is solved by the application of equalizer matching method .At last ,the effec‐tiveness of the proposed optimization test method is verified by a lot of simulation experiments and test results .This optimi‐zation test method is more effective than traditional method ,and it provides optimized ideas for future work .
