Abstract

Considers the cancellation of surface clutter returns from the composite surface/subsurface signal received by a low frequency nadir looking pulsed radar sounder. The two considered techniques are Doppler filtering for along track clutter cancellation and dual-antenna processing for cross track clutter cancellation. The improvement factor due to the application of the cancellation techniques is derived as a function of various operative parameters
