The normal sonar system rotates its beam, either continuously or under the operator's control, and the position of maximum response to a particular echo is taken as the bearing of the target.
The model of radar target is composed of distance, bearing, speed, heading and amplitude of echo, fluctuation.
目标模型包括船舶的距离、方位、速度和回波幅度、幅度起伏。
