An ISAR Jamming Method Based on One-bit Sampling and Convolution Modulation

Based on convolution modulation jamming, an ISAR jamming method combining one-bit sampling and convolution modulation is proposed. Starting from the principle of one-bit sampling, the mathematical principle of one-bit sampling is introduced in detail, and the characteristics of one-bit sampled signal are discussed. The mathematical principle of convolutional modulation jamming is presented, and it is pointed out that deceptive jamming can be produced according to the choice of video signals involved in convolution. Then, the mathematical derivation of one-bit sampling combined with convolution modulation jamming is presented, and the expression of jamming signal is obtained. Finally, the false target template is selected to simulate the deceptive jamming. The simulation results verify the correctness and effectiveness of the proposed method. The jamming method can greatly reduce computation complexity and save the cost.
