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.
