Abstract
Sub-Nyquist sampling jamming has become a common means in ISAR countermeasure to generate multi- false target images. In this paper, sub-Nyquist sampling jamming against bistatic ISAR with V-style modulation (V-FM) signal imaging is presented. The jamming signals, which are formed by the intercepted radar signals under the sub-Nyquist sampling theorem and scattered by moving targets, are collected to achieve high resolution range profile (HRRP) by dual-channel dechirping and take Fourier transform to obtain final false target images, analyze the influence of imaging results by sub-Nyquist sampling rate and bistatic angle. Simulated trails are used to validate the correctness of the analyses and the finally well-focused false-target images greatly support the effectiveness of the sub-Nyquist sampling idea in the countermeasures of VFM Bi-ISAR.
