摘要/Abstract

摘要： 在微波暗室内构建了一种实用的P波段后向散射测试系统。利用矢量网络分析仪发射步进频率信号，通过傅里叶变换得到目标高分辨率时域响应，然后采用多种信号处理技术消除目标区外的杂波干扰；经过处于非光学区的金属球定标后，获得了P波段的高精度雷达散射截面（RCS）测试数据。实验通过多个目标的对比分析，验证了系统的精度可优于1 dB。

Abstract: A practical backscattering measurement system on P-band is constructed in an anechoic chamber.Stepped-frequency signal is transmitted to gain high resolution time-domain response.The clutters out of target area are removed by some DSP techniques.After calibration with a metal sphere at the non-optical region，accurate Radar Cross Section（RCS） on P-band can be obtained.In the experiments，the results of four different objects waved less than 1 dB are gained.

Key words: backscattering measurement system, P-band, anechoic chamber, stepped-frequency signal, radar cross section
