A Framework for Compound Interrupted Sampling Repeater Jamming Parameter Measurement
Qinzhe Lv, Liyi Liu, Yaojun Wu, Mimi Peng, Yinghui Quan · IEEE Transactions on Instrumentation and Measurement · 2025
Active compound jamming, particularly compound interrupted sampling repeater jamming (ISRJ), possesses excellent flexibility and jamming effectiveness, making it one of the major threats to radar systems. Accurately measuring the key parameters of each ISRJ component within the compound ISRJ can provide critical prior information for subsequent anti-jamming efforts. However, most of the existing ISRJ parameter measurement methods target a single ISRJ and lack in-depth research on the measurement of compound ISRJ parameters. Therefore, we propose a unified framework for compound ISRJ parameter measurement that contains a compound ISRJ separation network based on an encoder-decoder architecture and a parameter regression module for measuring the key parameters of each ISRJ component in the compound ISRJ. Experimental results indicate that the proposed framework achieves parameter measurement accuracies of over 89% and 85% for dual-compound and multicompound ISRJ, respectively, significantly outperforming existing methods.
