A Study of Ground Clutter Suppression with a Regression Filter

2006 8th international Conference on Signal Processing, 2006
This paper explores the realization and computational complexity of the regression filter for ground clutter suppression. Ground clutter suppression performance of regression filter is compared with an existing ground clutter filter now used in CINRAD WSR-98D.

Ground clutter simulation for surface-based radars

Proceedings International Radar Conference, 2002
This paper presents a site specific ground clutter simulation developed for ground-based radars. The simulation provides clutter power maps according to digital terrain relief and landcover information. The comparison between simulated clutter and actual clutter shows that a good accuracy in clutter simulation can be achieved even for complex ...

Imaging of moving target in strong ground clutter

2001 CIE International Conference on Radar Proceedings (Cat No.01TH8559), 2002
The imaging method of a low-altitude target in strong ground clutter is presented. The identical amount of stretching time-delay with the adjoined echoes is applied in the signal stretching process, and then the ground clutter is filtered through the one-order canceller.

The study of radar ground clutter simulation based on DEM

2013 IEEE International Conference on Information and Automation (ICIA), 2013
A simulation method of radar ground clutter base on the Digital Elevation Model is proposed in this paper. In this article we adopt the method of random midpoint displacement to produces the elevation data of random terrain. Through the elevation data, the ground is split up into much geometry scattering surface unit with scattering property. The power

Adaptive polarisation for rejection of ground clutter

1989
This paper reports some results on adaptive polarization techniques for rejection of ground clutter. The analysis is based on measurements carried out with a low resolution radar equipped with a diversity polarization receiver and recorded through a suitably designed acquisition system. The polarization behavior of the recorded ground clutter phenomena

Effect of Range and Doppler Ambiguities on Ground Clutter

1998
In the last chapter, the sources of ground return and its acquaintance with its Doppler spectrum was surveyed. The profound effects of range and Doppler ambiguities on ground return was not considered. In this chapter, after briefly considering the dispersed nature of ground clutter, the effects of ambiguities on the range and Doppler profiles for a ...
