Robust Detection of Moving Human Target in Foliage-Penetration Environment Based on Hough Transform [PDF]

, 2014
Attention has been focused on the robust moving human target detection in foliage-penetration environment, which presents a formidable task in a radar system because foliage is a rich scattering environment with complex multipath propagation and time ...

Radar Detection in Compund-Gaussian Clutter

, 2004
In this paper, we study the adaptive version of the asymptotical Bayesian Optimum Radar Detector (BORD) built with a covariance matrix estimate. We investigate its properties, when the noise is modelled as a non-Gaussian complex process, such as Spherically Invariant Random Process (SIRP).

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 ...

Short-Range Nonstationary Clutter Suppression for Airborne KA-STAP Radar in Complex Terrain Environment

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Due to the range ambiguity effect and the complex terrain environment, the remote weak target of interest for nonsidelooking airborne radar is usually superimposed with the nonstationary and heterogeneous short-range strong clutter, so it is difficult ...

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 ...
