Abstract: Aiming at deceptive jamming method based on digital image synthetic (DIS) for inverse synthetic aperture radar imaging, the lack in engineering realization of anti-DIS deceptive jamming method based on variation of frequency modulation rate was analyzed and improved method for anti-DIS deceptive jamming based on compressed sensing theory was put forward. The improved method adopted compressed sampling based on random selecting and sparsity reconstruction method in compressed sensing into signal receiving and processing department in the foregoing method, and engineering practicability for anti-DIS deceptive jamming method based on variation of frequency modulation rate was improved. Simulation revealed validity of the improved method.
