Abstract

The clutter rejection of pulsed signals is analysed for short-range radar of centimeter and millimeter bands of radiowaves. The signal to clutter ratio (SCR) for uncoded pulsed sequence and pulse-compression signals is estimated. It is shown that for radars operating over the land and sea surface the use of wideband signals does not result in an improvement in the clutter rejection in comparison with the uncoded pulsed sequence. This rejection gets worse when the resolution cell dimensions of pulse-compression radar are compared with the range to the target.
