摘要：
Electromagnetic jamming can seriously affect the quality of synthetic aperture radar (SAR) images and pose significant obstacles to image interpretation. The additional degrees of freedom brought by multistatic SAR considerably contribute to the accurate extraction of jamming information. In this paper, a jamming detection and jammer localization method for the interrupted sampling repeater jamming (ISRJ) is proposed. First, the jamming components in multistatic SAR images are detected by utilizing the time delay characteristics of ISRJ. Then, based on the Doppler frequency invariance property of jamming, a system of equations for multiple receiving configurations is solved for jammer localization. The effectiveness of the proposed method is demonstrated through simulation.
