基于矢量网络分析仪的RCS测量系统及应用

RCS Measurement System based on Phasor Network Analyzer

目标散射截面(RCS)的测量是雷达目标识别、成像等研究领域的一个关键环节。在对目标RCS测量原理分析的基础上,提出了一个基于矢量网络分析仪测量目标RCS的测量系统。通过对几个实际目标RCS的测量,说明了该系统不仅结构简单,测量方便,而且功能强大,测量精度高。

Target radar cross section measurement is important in many u , and radar imaging. Based on the principle of RCS measurement, a system for RCS measurement in microwave anechoic chamber is presented. The measurement system mainly takes advantage of the powerful functions of phasor network analyzer that can act not only as sigmal transmitter and receiver but also as a precision measurement instrument in the system. The RCS for several special targets were measured using the proposed system. The results show that the system has powerful measurement function, high measurement accuracy, simplicity and feasibility compared with normal measurement system.
