摘要
信息作战环境日益复杂,而雷达信号分选技术是作为现代信息对抗领域的重要发展方向之一,对于雷达侦察非常重要。对于雷达信号分选,基于PRI参数提出了很多分选方法。传统的PRI变换能克服直方图统计法中的子谐波问题,但抗抖动性差。讨论了修正的PRI变换分选算法,有效地克服了传统PRI变换的缺点,并对算法进行了计算机仿真。最后还讨论了重频参差抖动脉冲序列的分选方法。
With the signal environment of information warfare increasingly complicated, the radar signal sorting technology, as one of development directions of modern radar, is of great importance to radar reconnaissance. Several radar signal deinterleav-ing methods are proposed based on PRI parameter. The traditional PRI transform can overcome the subharmonic problem pro-duced in the histogram statistic methods, but has a poor performance on anti-jitter. The paper begins with a discussion of the im- proved PRI transform which overcomes the disadvantages of traditional PRI method effectively, followed by the description of the algorithm simulation. Finally, a method for sorting pulse repetition intervals of staggered PRI is discussed.
