【摘要】：针对传统雷达信号分选方法在复杂环境下对于信号形式的适应能力不强的问题,提出基于内插采样的雷达信号分选方法。该方法通过设立两个侦察站,利用内插采样法高精度地测得雷达脉冲到达两站的时间,求取到达两站的时间差,根据不同雷达的信号到达两站的时间差不同完成信号分选。理论分析和计算机仿真表明,该方法能够有效地分选信号,对雷达信号具有较强的适应性,较好地解决了制约雷达对抗情报获取中的信号分选难题。
[Abstract]:In view of the traditional radar signal sorting method in complex environment for the signal in the form of adaptive ability is not strong, the radar signal sorting method based on interpolating sampling. This method through the establishment of two reconnaissance stations, using interpolation sampling method with high precision measured radar pulse arrival time for two stations, two stations arrive the arrival time difference, two station time according to different radar signal difference to complete signal sorting. Theoretical analysis and computer simulation show that this method can effectively separate the signal, and has strong adaptability to the radar signal, solves the problem of signal sorting control radar against obtaining intelligence.
