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.

普通声纳系统旋转它的电波，可连续或根据运营商的控制，以及对特定回波的最大响应状态被记录为与目标间的联系。

Usually, conventional incoherent weather radar is used to provide only the information on the position of a weather target and its radar reflectivity by detecting echo intensity.

通常非相干的常规天气雷达的应用仅仅是通过雷达回波强度的探测来提供天气目标物的位置和其反射率的信息。
