A radar extended target angle estimation method based on effective phase clustering
The Journal of Engineering, Volume 2023, Issue 12, December 2023., 2023 Multiple scatter points detected from extended targets in high‐resolution radar systems are often difficult to match with real target points due to uncertain factors such as clutter and system noise. To address this issue, this paper introduces the concept of effective phase and proposes a direction of arrival (DOA) angle estimation method for extended

Moving target detection method based on CUR‐RPCA for missing array elements
IET Radar, Sonar &Navigation, Volume 16, Issue 12, Page 2089-2103, December 2022., 2022 Abstract Moving target detection performance is seriously affected by missing array elements for multichannel synthetic aperture radar (Multi‐SAR) systems. Meanwhile, there is a contradiction between the accuracy of data recovery and the computational burden in traditional methods.

Electronics Letters, Volume 58, Issue 8, Page 324-326, April 2022., 2022 Abstract Due to the azimuth shift and defocus of the moving targets in the synthetic aperture radar image domain, a new synthetic aperture radar ground moving target indication method is proposed in this letter based on the changes of moving targets’ polarization characteristics before and after clutter suppression. This method can effectively suppress
