摘要
根据激光告警实际需求,开展混合激光制导信号的分选与解码研究。分析了混合激光制导信号特征,提出了混合激光制导信号分选和解码方法,编写了混合激光制导信号分选与解码软件。对PRF与PRF、PRF与PIM、PIM与PIM等三类混合信号进行了分选和解码。结果显示,利用骨架周期分析方法,能够正确分选包含PIM信号的混合信号,且分选与解码总用时较短,能够满足实际需求。
Based on the actual needs of laser warning,research on sorting and decoding of mixed laser-guided signals is studied in this paper.The feature of mixed laser-guided signals was analyzed,a new method to sort the mixed signals was proposed,and the sorting and decoding software of mixed laser-guided signals was written.Three kinds of mixed signals were sorted and decoded using this software,which contain PRF(Pulsed Repetition Frequency)mixed PRF signals,PRF mixed PIM(Pulse Interval Modulate)signals,and PIM mixed PIM signals.The results showed that the mixed signals which contain PIM signal could be sorted and decoded correctly by using the method of frame cycle analysis,and the total time for sorting and decoding is short,which can meet the actual needs.
