Attack Error Analysis of Helicopter′s Torpedo Guided by Surface Ship

In the anti-submarine warfare (ASW) scenario, the errors of a helicopter′s torpedo guided by surface ship concerns guiding ship′s position error, course error, velocity error, detecting distance error, and detecting bearing error, as well as helicopter′s position error, attack course error, and attack velocity error. By analyzing transferring process of the above errors, we calculate the influences of these errors on attacking effect by using Monte Carlo method, and conclude that the navigating and positioning precisions of the guiding and attacking platforms impose significant influence on torpedo attacking effect.
