摘要

相干周期波形的多普勒处理通常采用n脉冲(或n周期)消去器，然后是加权FFT。早期运动目标检测(MTD)使用一个简单的3脉冲抵消器作为MTI滤波器。地基雷达MTD面临着杂波衰减与慢速目标可见性的矛盾。本文建议对三脉冲消去器进行两种简单的修改，以缓解这种冲突。在静止杂波中检测非常慢的目标在边界或周界防护中具有重要意义。

Adjusting 3-pulse canceller to enhance slow radar targets

Doppler processing of a coherent periodic waveform usually employs an n-pulse (or n-period) canceller followed by a weighted FFT. Early moving target detection (MTD) used a simple 3-pulse canceller as the MTI filter. MTD in ground-based radar faces a conflict between clutter attenuation and slow targets' visibility. The paper suggests two simple modifications to a 3-pulse canceller that will ease this conflict. Detecting very slow targets within stationary clutter gains importance in border or perimeter safeguarding.
