Abstract : Radar detection of aircraft on a particular scan depends in large measure on the clutter return from the target's range cell. The distribution of clutter reflectivities is often so wide that variations of many dB in signature or threshold of detection correspond to changes of only a few percent in PD (probability of detection).

An experimental classification of radar clutter
Proceedings of the IEEE, 1979This letter describes some experimental results concerning the classification of radar clutter-according to whether it is due to reflections from ground, weather disturbances, or migrating flocks of birds. The procedure is based on the maximum entropy method.

On the Mechanisms of Radar Sea Clutter
Proceedings of the IRE, 1957Experimental data on radar sea clutter are described and discussed with reference to the physical principles involved. It is shown that the scattering elements are illuminated by a combination of direct and indirect fields, the latter being "reflected" by surface elements closer to the radar.

Detection in Heterogeneous Radar Clutter
2007 IEEE 15th Signal Processing and Communications Applications, 2007Classical algorithms that were derived with Rayleigh clutter assumption yield increased false alarm rate under Weibull clutter. In this study, a method for radar thresholding in range-heterogeneous Weibull radar clutter is proposed. The method employs expectation-maximization (EM) algorithm in estimation of the parameters and sets the threshold ...

The characteristics of radar sea clutter
2006In this chapter, sea clutter is described in terms of its observed characteristics. These observations will provide the foundations upon which the themes of subsequent chapters are developed. Radars operating in a maritime environment inevitably encounter backscattered radar signals from the sea surface, usually referred to as sea clutter.

Clutter suppression in search radars
1977 IEEE Conference on Decision and Control including the 16th Symposium on Adaptive Processes and A Special Symposium on Fuzzy Set Theory and Applications, 1977A comparison of MTI and Optimum Pulse-Doppler processors is presented for the case where they coherently process the same number of pulses in a radar dwell. These results are presented in terms of probability of detection versus signal-to-noise or signal-to-clutter ratio, for a fixed false alarm probability.
