A Knowledge-Based Auxiliary Channel STAP for Target Detection in Shipborne HFSWR
The broadened first-order sea clutter in shipborne high frequency surface wave radar (HFSWR), which will mask the targets with low radial velocity, is a kind of classical space–time coupled clutter.

The ground and sea clutter received by space-based early warning radar (SBEWR) has severely range ambiguous characteristics due to its platform location, and the non-stationary factor caused by Earth’s rotation makes the received clutter at different ...

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 ...

Radar clutter suppression schemes
In the letter the spatial correlation between radar clutter returns from adjacent range rings is exploited to construct two new adaptive clutter suppression schemes. The schemes are tested by using actual radar data, including weather clutter as well as ground clutter.

Knowledge-Aided Multichannel SAR Clutter Suppression Algorithm in Complex Scenes
Multichannel synthetic aperture radar (SAR) achieves high-resolution imaging while significantly enhancing the spatial freedom of the SAR system. As SAR hardware performance continues to improve, observed scenes often transition from simple to complex ...
