Study of Ranging Method and Hydrophone Deploying Scheme of Ranging Torpedo Hitting

摘要

Synchronization ranging method is usually used in the ranging of torpedo hitting when the torpedo has cooperancy beacon. If the torpedo has no cooperancy beacon, the ranging of torpedo hitting can be estimated with the torpedo noise incepting and analyzing. The two ranging method are discussed and the hydrophone deployment scheme are studied in this paper. By analyzing the target state attacked by the torpedo, the hydrophone deploying schemes of four points ranging and two points ranging are put forward. The ranging of torpedo hitting can easily realized with the coordinate conversion, center method and least distance method. The minim error of two points ranging can be revised with the help of depth information.
