Radar clutter suppression schemes
Electronics Letters, 1984 In the letter the spatial correlation between radar clutter returns from adjacent range rings is exploited to construct two new adaptive clutter suppression schemes. The schemes are tested by using actual radar data, including weather clutter as well as ground clutter.

Modified matched filter for cloud clutter suppression [PDF]
IEEE Transactions on Pattern Analysis and Machine Intelligence, 1990 The least-mean-square (LMS) filter has been developed as an alternative to the classical matched filter (MF) to address the clutter-spectrum issue. However, the output of the MF and the LMS processes is dependent on the scene energy and marginally dependent on the filter signal shape.

Surface Clutter Suppression Techniques for Ice Sounding Radars: Analysis of Airborne Data [PDF]
, 2008 For the ice sounding of Antarctica from space, a P-band radar at 435 MHz is the only option which complies with present ITU regulations. At this frequency the ice surface cannot be considered smooth, leading to high ambiguous returns.
