Abstract
The clutter rejection of pulsed signals is analyzed for short-range radar using centimeter and millimeter bands of radiowaves. The signal to clutter ratio (SCR) for uncoded pulsed sequences and pulse-compression signals is estimated. It is shown that the use of wideband signals for radars operating over the land and sea surface does not improve the clutter rejection over that obtained with the uncoded pulsed sequence. In addition, this rejection degrades as the resolution cell dimensions of pulse-compression radar approach the range to the target.
