Bistatic SAR Clutter-Ridge Matched STAP Method for Nonstationary Clutter Suppression
IEEE Transactions on Geoscience and Remote Sensing, 2022Clutter suppression is a challenging task in synthetic aperture radar-ground moving target indication (SAR-GMTI). In general, sufficient secondary samples are not easily acquired due to the non-stationary and non-homogeneous characteristics of bistatic SAR (BiSAR) clutter, resulting in worse clutter suppression results.

Clutter Suppression for Wideband Radar STAP
IEEE Transactions on Geoscience and Remote Sensing, 2022Traditional space-time (ST) adaptive processing (STAP) theory is based on the assumption of narrowband or ``zero-bandwidth,'' where the decorrelation within the ST snapshot is ignored. However, with radar bandwidths increasing, this assumption becomes invalid due to the deteriorated decorrelation of the received signals within the ST snapshot.

A block adaptive approach for clutter suppression
ICASSP '85. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005A new technique for the adaptive suppression of clutter signals and narrow band interference in pulse doppler radar system is presented. In this new technique two filters F1 and F2 in cascade are used, where the filter weights of F2 are updated from the filter weights of F1.

Wideband waveform design for clutter suppression
2014 IEEE 8th Sensor Array and Multichannel Signal Processing Workshop (SAM), 2014Modern signal generators offer the capability to synthesize arbitrary wideband waveforms for radar and sonar applications. This makes it possible to optimize signals for specific purposes or scenarios. Herein, we discuss how to design a wideband waveform for clutter suppression.

Suppression of ground and weather clutter
IEE Proceedings F Communications, Radar and Signal Processing, 1981It is shown that Weibull-distributed weather clutter obeys a Weibull distribution after passing through a moving target indicator (MTI) processor realised by a double canceller. Both ground and weather clutter can be thus suppressed by using the method of MTI and new Weibull constant false alarm rate (CFAR) systems.

Adaptive radar clutter suppression
MTS/IEEE Oceans 2001. An Ocean Odyssey. Conference Proceedings (IEEE Cat. No.01CH37295), 2002The clutter return presents a severe problem in target detection for radar systems. Conventional radar systems assume the clutter is stationary, with energy concentrated in the low frequency domain. To minimize the effect of clutter, radar systems use a fixed high pass filter (HPF) to eliminate the clutter.

Clutter property analysis and clutter suppression for Hypersonic airborne radar
2013 International Conference on Radar, 2013Clutter property of a forward-looking array radar on Hypersonic Vehicle is analyzed and a method for clutter suppression using multi-stage space-time adaptive processing (STAP) is proposed. This method employs the elevation degree of freedom of the planar array to extract various range ambiguous clutter. Then range-unambiguous non-stationary clutter is
