| 摘 要： | 通过分析参差雷达信号的基本特征,针对PRI变换算法在参差雷达信号分选中存在的不足,提出了一种基于PRI谱内特征的参差雷达信号分选算法。该算法利用PRI变换获取信号的时域PRI谱,进而根据PRI谱内脉冲对数特征完成参差信号帧周期的分选工作。仿真结果表明,该方法能够较好地实现参差雷达信号的分选工作。

| Abstract: | In view of the basic signatures of radar signals and some deficiencies of the PRI transform algorithm in the signal sorting,a signal sorting algorithm based on the PRI spectrum signatures for staggered radars is presented.The time-domain PRI spectrum of the signals is obtained through the PRI transform,and the staggered signal sorting in the frame period is completed based on the signatures of the pulse logarithm of the PRI spectrum.The simulation results show that the algorithm is superior in realizing the... |
