摘要
依据鱼雷攻潜末弹道测量定位模型,对所接收鱼雷上加装的声信标脉冲序列结构进行仿真,并就如何从带有干扰的接收数据中挑选出直达脉冲进行研究。依此总结出的抗多途专家系统,有效解决了直达声脉冲识别难题,提高了测量精度。实验室测试表明,应用该专家系统的处理方法,测距直达脉冲和测深直达脉冲的正确选择概率超过95%。
The sequence structure of beacon signal in torpedo is simulated which base on the model of terminal trajectory-measurmet,and a method of selecting direct pulses from the complex received signal sequence is studied. The anti-mnhipath expert used for resolving the difficult problem of selecting the direct pulses is presented. By means of laboratory test, it is proved that the expert system can sort out the direct pulses effectively, and the accurate rate is more than 95 percent.
