Space-time Characteristics and Experimental Analysis of Broadening First-order Sea Clutter in HF Hybrid Sky-surface Wave Radar [PDF]

open access: yes, 2014
In high frequency (HF) hybrid sky-surface wave radar, the first-order sea clutter broadening is very complex and serious under the influence of ionosphere and bistatic angle, which affects the detection of ship target.

Clutter rejection for MTI radar using a single antenna and a long integration time [PDF]

open access: yes, 2011
Moving Target Indicators (MTI) are airborne radar systems designed to detect and track moving vehicles or aircrafts. In this paper, we address the problem of detecting hazardous collision targets to avoid them.

Multi‐Frame Coherent Integration for Detecting High‐Speed Manoeuvring Target in Bistatic Space‐Based Early Warning Radar

open access: yesIET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
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 ...

A Space‐Time‐Frequency Adaptive Processing Method for Dual‐Band Airborne Radar in Complex Electromagnetic Environments

open access: yesIET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
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

open access: yesThe Journal of Engineering, 2019
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-

Range Ambiguous Clutter Rank Estimation in Airborne Element‐Pulse Coding‐Multiple‐Input Multiple‐Output Radar

open access: yesIET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
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

Clutter Suppression Approach for End-Fire Array Airborne Radar Based on Adaptive Segmentation

open access: yesIEEE Access, 2019
End-fire array antenna is a kind of special radar antenna with beam pointing perpendicular to the normal direction of the array. Because of its low profile and directional radiation characteristics, it is especially suitable for blind zone compensation ...
