| 摘 要： | 本文根据某型气象雷达的性能要求,提出了一种分频段跟踪的AFC系统方案,有效地解决了大范围跟踪、跟踪精度与接收机镜频抑制之间的矛盾,并且用一个一阶环路模型对系统跟踪误差进行了理论分析,分析结果与工程实践均证明本方案是可行的。

| Abstract: | Basing on performance reguirements of weather radar, this paper presents a version of automation freguency control (AFC)system according to the divided frequency range tracking. This version solved efficiently contradicticn between the large trackina, tracking accuracy and image freguency suppression of receiver. In the paper,tracking error of the system is analyzed by use of an order loop pattern. Analytical result and engineering practise show that this version is feasible. |
