摘要:
通过平面变换技术将雷达脉冲映射成平面矩阵,在分析周期信号在平面矩阵中重复特性的基础上,提出了一种周期性雷达信号分选的新方法——矩阵匹配法.针对以前搜索算法门限确定困难以及当信号密集且周期性信号数量较少时无法分选的缺点,该算法采用通过检索相似度序列的方法,实现自动分析最小显示周期并完成分选工作.仿真表明该方法对周期信号具有很高的分选准确度,对PRI随机抖动雷达也具有一定分选能力.该算法检索速度快、计算简单且易于实现,具有广泛的工程应用前景.
Abstract:
The paper proposed a new method for periodical radar signal deinterleaving, named matrix matching method. With this method, the radar pulses are mapped into planar matrix via planar transformation. The former deinterleaving methods have the problem of setting the threshold value; moreover, when the signal is dense or sparse, it almost cannot be deinterleaved. This algorithm analyzes the minimal PRI automatically by matching the similar sequences, so it can overcome these problems. Simulation shows that this algorithm can deinterleave the periodic radar signal effectively and has the ability to sort the radar signals of PRI jitter. This new algorithm is fast and easy to realize, and has a broad engineering application prospects.
