波束稳定是舰载测量雷达区别于岸基测量雷达的主要特点和要求,伺服系统需要克服船摇保持波束稳定。在工程设计中,回路参数设计是伺服系统设计的重要环节。详细阐述根据船摇隔离度、回路带宽等指标要求,重点分析位置跟踪回路、船摇稳定跟踪回路的参数设计方法和过程。理论计算和工程实践证明,雷达能较好地克服船摇影响,稳定跟踪快速目标。

Keeping steady wave beam is the main characteristic and request of ship-based measuring radar, which distinguishes with shore-based radar. Servo system must overcome the swinging ship to keep steady wave beam. In engineering design, loop parameter design is the most important point to servo system design. Based on the request of isolation degree of the swinging ship index, loop bandwidth index and so on, this article states the means and process in detail, which is used for designing the parameters of analysis of position tracking loop, and the swinging ship stabilization loop. The computing and engineering practice proved that, radar can excellently overcome the influence of swinging ship, furthermore, track the fast object stably.
