Polarimetric Adaptive Coherent Detection in Lognorm-Texture-Distributed Sea Clutter

Remote Sensing
This paper addresses polarimetric adaptive coherent detection of radar targets embedded in sea clutter. Initially, radar clutter data across multiple polarimetric channels is modeled using a compound Gaussian framework featuring an unspecified speckle ...

Clutter Mitigation in Indoor Radar Sensors Using Sensor Fusion Technology

Sensors
A methodology utilizing low-resolution camera data is proposed to mitigate clutter effects on radar sensors in smart indoor environments. The proposed technique suppresses clutter in distance–velocity (range–Doppler) images obtained from millimeter-wave ...

Ship Echo Discrimination in HF Radar Sea-Clutter

, 2003
International audienceHF radar can provide Over the Horizon detection of ships on very large oceanic areas, making use of the ionospheric refraction of radio waves. The Doppler spectrum of the sea clutter is composed of the first-order Bragg lines with a

Space-Doppler processing for multichannel ISAR imaging of non-cooperative targets embedded in strong clutter

, 2013
Non-cooperative moving targets appear defocussed in SAR images and the blurring effect due to the unknown motion leads to low detection capabilities.

Clutter Detection in Radar Applications

, 2020
Radars have been used for detection purposes in safety applications (i.e., blind spot detection radar in cars) extensively. The existing detection methods, however, are not flawless. So far, the main focus of these methods is on detecting an object based on its reflectiveness.

Amplitude Suppression of Nongaussian Sea Clutter in a Coherent Bandpass Path of the Receiver

Известия высших учебных заведений России: Радиоэлектроника, 2016
The method of non-linear amplitude suppression of radar clutter from a sea surface in the coherent band path of the receiver is considered. The model of the most adequate nongaussian radar clutter from the rough sea surface which envelope is based on K ...
