Deception Jamming Method for ISAR Based on Sub-Nyquist Sampling Technology

摘要：

Fast sampling of wideband RF signal and real time processing of vast data are great difficulties in the engineering implementation of deception jamming to ISAR. This paper proposes a sort of Sub-Nyquist Sampling-Based Method for Jamming ISAR Systems. First introduces the deception jamming technique based on false target for ISAR. Then investigates the jamming principle of sub-Nyquist sampling modulation. Through modulating false target information on radar signals intercepted by sub-Nyquist sampling, the resulting signal can produce a train of vivid false targets. The proposed method can greatly reduce the demands on sampling rate and processing speed, its jamming performance is analyzed in detail and verified by simulation experiments. The conclusions here have certain significance to the manufacture of ISAR jammer in practical engineering.
