摘要

在相位编码雷达进行各目标回波信号功率相差较大的多目标或隐身目标检测时

会存在隐身目标和小功率信号淹没在大功率信号距离旁瓣中的情况.本文提出了一种逐次消去回波中大功率信号的方法来去除大功率信号的距离旁瓣

检测小功率信号

从而提高雷达系统观察目标的动态范围至80dB以上.仿真研究和雷达实验表明该方法是有效可行的.

Abstract

When the phase-coded radars scan the stealth targets or numerous targets

which have large changes in their echo amplitudes

the weaker signals may be drowned in the range sidelobe caused by the stronger signals.A step by step way of removing the stronger signals from the echoes to eliminate their range sidelobe is presented

so that the weaker signals can be detected and the dynamic range of the radar system can be enhanced by 80dB or more.Simulation study and radar experiment indicate that the method is effective and feasible.
