Space-Time Adaptive Processing by Employing Structure-Aware Two-Level Block Sparsity
Traditional radar space-time adaptive processing (STAP) cannot efficiently suppress heterogeneous clutter because of a small number of independent and identically distributed training snapshots.

A Joint Sparse Space-Time Adaptive Processing Method
At present, most of the sparse space-time adaptive processing(STAP) methods focus on exploiting the clutter sparsity. In this paper, different from the present sparse STAP methods, both the clutter sparsity and the target sparsity in STAP are considered ...

This paper presents a long‐time coherent integration framework for bistatic space‐based early warning radar (SBEWR) systems, combining both intra‐frame and inter‐frame integration. To address challenges such as range and Doppler cell migration, phase inconsistencies and strong clutter, the proposed method first applies space‐time adaptive processing ...

Robust Covariance Matrix Estimation for Radar Space-Time Adaptive Processing (STAP)
Estimating the disturbance or clutter covariance is a centrally important problem in radar space time adaptive processing (STAP). The disturbance covariance matrix should be inferred from training sample observations in practice. Large number of homogeneous training samples are generally not available because of difficulty of guaranteeing target free ...

In this paper, we first establish the dual‐band airborne radar wideband echo signal model and propose a space‐time‐frequency adaptive processing method based on it. Firstly, in the passive mode, the poles of the dual band are estimated by the matrix pencil method, and the incoherent components are estimated through the phase relationship between the ...

Anti-jamming method for STAP based on a bi-phase random-coded signal
The scattered-wave sweeping frequency jamming occupies many space-time adaptive processing (STAP) degrees of freedom, which results in a serious decline in STAP performance. To solve this problem, an anti-jamming method of STAP based on a bi-phase random-

This paper analyzes the clutter rank under range ambiguity in EPC‐MIMO radar. ABSTRACT Space‐time adaptive processing (STAP) with element‐pulse coding (EPC)‐multiple‐input multiple‐output (MIMO) radars is capable of suppressing range ambiguous clutter in airborne radar fields. However, clutter rank has not been investigated in EPC‐MIMO radars, which is
