雷达信号分选实现的新方法

解决反辐射导弹在高密度复杂电磁环境下的雷达信号分选问题,提出一种雷达信号分选实现的新方法。采用关联比较器进行雷达信号预分选，在主分选中，应用修正的脉冲重复间隔(pulse repetition interval, PRI)算法测量雷达信号PRI。在硬件实现上提出一种非均匀设定PRI箱宽度的方法，可节省大量的运算时间，提高系统实时性。实验结果表明，该分选方法具有快速准确的优点，既解决了以往直方图统计算法中的子谐波问题，又克服了传统PRI算法不能有效分选抖动脉冲序列的缺点。

New method for sorting radar signals

To solve the problem existing in the sorting of the radar-signals under the high-signal-density and complex electromagnetic environment in the ARM,a new method of achieving sorting the radar-signals is presented.Using the coherent processor to pre-sort radar signals.In the main sorting,the modified PRI transform is used to measure the PRI of radar-signals.In the hardware,a method called non-uniform setting the width of PRI-box is put forward,which can save much running time of the algorithm to enhance the r...
