An Anti-deception Jamming Method for LFMCW Detector

doi:10.3969/j.issn.1000-1093.2019.04.010

Abstract

Abstract: An anti-radio frequency storage and repeater jamming method is proposed for the millimeter wave linear frequency modulation continuous wave (LFMCW) detection system for subsonic bomb detection, which is based on high-resolution range profile, chirp Z transform (CZT) spectrum zooming algorithm and dynamic time warping (DTW) matching algorithm. The multi scattering center target echo model and the jamming signal model based on the digital radio frequency memory (DRFM) are analyzed in the LFMCW detection system. On the basis of the constant false-alarm rate detection, the target signal spectrum is zoomed by CZT, and the feature of target HRRP is extracted. DTW matching algorithm is used to distinguish between the real target and the jamming target. The simulated and experimental results show that the obstructions detection method based on CZT and DTW can effectively distinguish between the real target and the jamming target based on DRFM for subsonic bomb-borne millimeter wave LFMCW detector.
