The mainlobe deceptive jamming has the same angle as the real target scene,and the two are highly similar in multiple domains,which seriously reducing the detection and judgment capabilities of the synthetic aperture radar system for real targets.To address this issue and ensure effective suppression of mainlobe deceptive jamming,a real-time and fast processing anti-main-lobe deceptive jamming algorithm is proposed in this paper.First,an echo recovery framework based on azimuth phase coding is proposed and the framework can group the raw echo data.Secondly,a fast algorithm for modular processing is proposed to speed up the processing efficiency of the proposed method.Finally,the effectiveness and feasibility performance of the proposed meth-od are verified through point target and distributed targets simulation experiments.By comparing with the traditional mainlobe de-ceptive jamming method,the proposed method can not only reduce the computational complexity,but also reduce the occupation of system resources.
