将前向散射（FS）概念转移到无源相干定位（FS PCL）系统提供了一个新的研究领域。本文致力于研究双基地无源相干定位系统在FS模式下的各个方面。为了有效地进行信号处理，提出了适当的FS PCL系统分析。研究表明，使用传统信号处理算法的相对较小的现代化，PCL系统可以有效地对抗穿越或位于雷达基线附近的隐身和低姿态目标。对FS信号进行了分析，找出了影响波形和频谱的关键因素和参数，这些因素和参数决定了整个信号处理过程。实验结果验证了所提出的分析。
The transfer of the forward scatter (FS) concept to passive coherent location (FS PCL) systems provides a new emerging area of research. This article is dedicated to the investigation of various aspects of a bistatic passive coherent location (PCL) system operating in the FS mode. For efficient signal processing, appropriate FS PCL system analysis is presented. It is shown that using a relatively small modernisation of traditional signal processing algorithms, a PCL system may effectively operate against stealth and low profile targets crossing or being located in the vicinity of the radar baseline. The FS signals have been analysed in view of finding key effects and parameters influencing the waveforms and spectra which define the overall signal processing. Experimental results are given to validate the presented analysis.
