Anti-multipath expert system for terminal trajectory-measurment of torpedo
Sun Xiang-qian · Ship Science and Technology · 2012
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-multipath 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.
