METHOD FOR PRODUCTION OF A DANGER WARNING AGAINST AN ATTACKING TORPEDO

摘要

The method involves pinpointing a torpedo with an underwater antenna using sonar under output of pinpointing angle and pinpointing time. The cotangent of the pinpointing angles is computed and the pinpointing time is assigned such that slew rate of the cotangent in a center pinpointing angle area is compared with a default value and an operating signal for a warning alarm is released if the cotangent exceeds the value.
