基于时宽抖动PN序列的直扩系统干扰方法

irect sequence spread spectrum (DSSS) signal has strong anti-interference ability, and how to effectively interfere with it becomes the key. In order to effectively interfere with the DSSS signal, at the same time solve the problem of the jamming effectiveness of traditional jamming is reduced under the conditions of various anti-jamming and the jamming effectiveness of related jamming depends on the high degree of synchronization, a jitter-related jamming technique is proposed. This method injects jitter on the pseudo-random sequence, so as to improve the value of correlation in the case of low synchronization degree, and then use the jitter pseudo-sequence modulation jamming signal to interfere with the DSSS signal. Theoretical analysis and simulation results show that the method can realize the efficient related jamming of the DSSS signal in the case of low synchronization degree, significantly improve the bit error rate. This method has an excellent jamming effectiveness.
