Abstract

Abstract:

To address the challenge of deception jamming identification, a real-false target discrimination algorithm is proposed for airborne distributed radar based on filter mismatch error correction and correlation coefficients. Firstly, the effects of various synchronization errors on the correlation of real and false targets are analyzed. Then, an accurately matched filter is constructed to eliminate mismatch errors. Subsequently, the correlation coefficients among all target signal vectors are calculated to construct a correlation coefficient matrix, which is quantified to distinguish true targets from false targets by leveraging the difference in correlation between real and false target signals. Finally, simulation results demonstrate that, compared to existing methods, the proposed algorithm achieves a lower false target misjudgment probability under the same conditions of true target recognition probability and jamming-to-noise ratio, verifying the effectiveness of the proposed algorithm.

Key words: deception jamming, distributed radar, synchronization error, real-false target discrimination
