Modelling real‐world effects in near‐field SAR collections for compressive sensing

IET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.
This paper develops previously published work on using compressive sensing techniques to suppress sidelobes in SAR images to develop a higher‐fidelity measurement model. Using Cranfield University's GBSAR System a series, experimental measurements are conducted, and image estimation techniques are applied to this real data.

A Novel Jamming Method Based on Micro‐Doppler Modulation and Electromagnetic Meta‐Materials

IET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.
In this paper, the jamming model based on the uniformly accelerated or decelerated rotating corner reflector and the electromagnetic meta‐materials is systematically discussed. Then, correctness of theoretical analysis is verified by simulations based on the airborne SAR echo data. Compared with the existing research, the jamming model proposed in this

A high precision estimation algorithm for multi‐channel wide‐area surveillance ground moving target indication mode based on maximum likelihood method

IET Radar, Sonar &Navigation, Volume 18, Issue 9, Page 1431-1443, September 2024.
A high precision estimation algorithm for ground moving targets in multi‐channel wide‐area surveillance ground moving target indication systems is proposed based on maximum likelihood method. The main concept of this novel algorithm is to estimate the azimuth angle of the detected targets using maximum likelihood method with the space steering vector ...
