Abstract :
Aiming at the de-correlation effect of echo phase in frequency agile radar (FAR) and the range cell migration problem in long time integration, the Frequency Agile Coherent Radon Transform(FA-CRT) is proposed to realize long time coherent integration for FAR. Firstly, the FAR echo model of moving target is established. Secondly, the FA-CRT method is brought forth. Finally, a numerical experiment is designed to verify the performance of FA-CRT in long time coherent integration.
