Fast clutter cancellation for noise radars via waveform design

Canceling clutter is an important, but very expensive part of signal processing in noise radars. It is shown that considerable improvements can be made to a simple least squares (LS) canceler if minor constraints are imposed onto noise waveform. Using a combination of field programmable gate array (FPGA) and CPU, the proposed scheme is capable of canceling both stationary clutter and moving targets in real time, even for high sampling rates.
