摘要
基于卫星信号的无源雷达系统具有诸多一般无源雷达系统所不具备的优势,但同时,低信噪比下如何检测出目标信号是该无源雷达系统的一个关键问题。本文从提高信噪比的角度来探讨了系统探测海面目标所需的增益,分析了影响系统处理增益的因素。
The bistatic (multistatic) radar system based on non-cooperative illuminators is superior to the classical radar in many aspects, but one of key problems is how to detect weak echoes signal under the condition of low SNR. The system processing gain is analyzed and the factors for influencing the system processing gain are discussed.
