Deterministic-aided single dataset STAP method based on sparse recovery in heterogeneous clutter environments

EURASIP Journal on Advances in Signal Processing, 2018
Traditional space-time adaptive processing (STAP) usually needs many independent and identically distributed (i.i.d) training datasets for estimating clutter covariance matrix (CCM).

Deceptive Jamming Suppression by Frequency‐Domain Adaptive Processing With Multi‐Carrier Radar

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
This paper proposes a frequency‐domain adaptive processing method based on the multi‐carrier radar to suppress deceptive jamming. Different from frequency diverse array‐multiple‐input multiple‐output (FDA‐MIMO) radars relying on spatial antenna arrays, the multi‐carrier radar obtains range‐dimension degrees of freedom through a single co‐located ...

Self-organizing adaptive radar space-time adaptive processing

, 2009
For radar on a moving platform, clutter spectrum spreads in the angle (space) domain as well as in Doppler (time) domain. Radar signal processing is done adaptively in both space and time domain to suppress clutter that is called Space-Time Adaptive ...

Reduced-Dimension FDA-STAP for Range-Ambiguous Clutter Rejection Under Limited Snapshots

Eng
Space-time adaptive processing (STAP) has been widely recognized as an effective technique for suppressing clutter in airborne radar systems. Nevertheless, range ambiguity can seriously affect the clutter rejection capability of conventional STAP methods.

Space‐Time Adaptive Processing Clutter Suppression Algorithm Based on Spatiotemporal Stationarity of Ionospheric Clutter in HFSWR

International Journal of Antennas and Propagation, Volume 2026, Issue 1, 2026.
In high‐frequency surface wave radar (HFSWR) systems, ionospheric clutter is a common phenomenon that often causes targets to be submerged. Space‐time adaptive processing (STAP) is a classical adaptive filtering algorithm. To reduce computational complexity and the required number of clutter samples, practical radar systems usually employ reduced ...

Local Degree of Freedom of Clutter for Reduced-Dimension Space-Time Adaptive Processing with MIMO Radar

International Journal of Antennas and Propagation, 2018
Degree of freedom (DOF) of clutter in the reduced-dimension (RD) domain, which is called local DOF (LDOF), is of great importance for RD MIMO-STAP (space-time adaptive processing for multiple-input multiple-output radar) algorithms.
