【Abstract】 As for the problem of the torpedo localization and range measurement based on R-R bistatic sonar. Firstly, the effect law of ranging accuracy caused by the precision of the direction of arrival(DOA) estimation and the baseline measurement between the two sonars are studied. And then, a localization method using R-R bistatic sonar based on the least squares estimation is proposed. The numerical simulation shows that, the passive ranging method using the least squares estimation method is valid, which can track the target track effectively, and the ranging accuracy is associated to the DOA estimation precision and the baseline spacing.更多还原
