Efficient Methods of Clutter Suppression for Coexisting Land and Weather Clutter Systems [PDF]
The removal of coexisting land and weather clutter signals is a common problem in many radar applications. Although the optimal method for land-weather clutter suppression is known, it is usually not amenable to implementation due to computation and storage limitations of the processor.

Eigen-based clutter filters for color flow imaging: Single-ensemble vs. multi-ensemble approaches [PDF]
In designing eigen-based clutter filters for color flow imaging, one of the challenges is to develop an accurate way of estimating the eigen-components that represent clutter in slow-time ensembles.

Robust knowledge-aided sparse recovery STAP method for non-homogeneity clutter suppression
Conventional space–time adaptive processing (STAP) methods would suffer severely performance loss in the complex clutter environment of an airborne-phased array radar, especially when the estimated clutter covariance matrix (CCM) is corrupted by the ...

Distribution Characteristics of Ground Echo Amplitude and Recognition of Signal Grazing Angle
With the continuous advancement of electronic technology, terahertz technology has gradually been applied on radar. Since short wavelength causes severe ground clutter, this paper studies the amplitude distribution statistical characteristics of the ...

Fast-time STAP performance in pre and post range processing adaption as applied to multichannel SAR [PDF]
Hot-clutter cancellation using fast-time Space Time Adaptive Processing (STAP) can occur either pre or post range processing (RP) and to date, there has not been a direct comparison on which method offers the best results. This paper provides an analytic
