Clutter suppression scheme for vehicle radar

2010 IEEE Radio and Wireless Symposium (RWS), 2010
Vehicle radar receives echoes from the natural environment such as road and building. These echoes are called clutter which can be much higher than vehicle echo. It is therefore expect to improve the detection performance by summing all the radar echoes available from the vehicle.

Wideband waveform design for clutter suppression

2014 IEEE 8th Sensor Array and Multichannel Signal Processing Workshop (SAM), 2014
Modern 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.

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, 1977
A 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.

SAR clutter suppression using recursive waveforms

2015 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2015
In this paper, we combine the waveform design method with the synthetic aperture algorithm to suppress clutter and generate clear microwave images of targets. The linear recursive model is introduced into the SAR operation principle and Kalman filter algorithm is used to estimate target and clutter responses in each azimuth direction based on their ...

New clutter suppression approach for multifunction radar-radar resource management for the clutter suppression

IEEE Aerospace and Electronic Systems Magazine, 1990
The use of constant-false-alarm-rate (CFAR) techniques to keep false alarm rates at a suitable low level is reviewed. Radar resource management for clutter suppression, a novel approach for multifunction phased-array radar that can more effectively suppress clutter, is proposed.

Clutter-Ridge Matched SR-STAP Technique for Non-stationary Clutter Suppression

2020 IEEE Radar Conference (RadarConf20), 2020
Non-stationary clutter suppression is an attractive and challenging problem in space-time adaptive processing(STAP) algorithms. Although sparse recovery(SR) STAP can effectively alleviate strong clutter non-stationary characteristic with a few number of samples, there are still difficulties where the clutter components are not located on the discrete ...

IR Polarization for Natural Clutter Suppression

2018 IEEE Research and Applications of Photonics In Defense Conference (RAPID), 2018
IR Polarization can help to find man-made objects in scenes primarily made up of the natural environment. A model was developed to predict and explain results in short range, on-the-move situations. Test results show that Polarization contrast nearly always exceeds radiance contrast and generally suppresses background clutter.

Suppression of Weibull clutter

1990
The suppression of radar clutter is a very important problem in modern radar technique, and is discussed in many papers and books. We are not going to discuss this problem in general, but will discuss some special problems concerned with Weibull clutter.

Radar clutter suppression using adaptive algorithms

2004 IEEE Aerospace Conference Proceedings (IEEE Cat. No.04TH8720), 2005
Radar clutter is the extraneous return waveform from the radar background environment. Because the clutter has a large cross-section, radar clutter can seriously degrade target detection. Conventional radar systems assume the clutter is stationary with its energy concentrated at low frequencies.

Suppression of ground and weather clutter

IEE Proceedings F Communications, Radar and Signal Processing, 1981
It 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.
