摘要
频率综合产生器(频综)是CINRAD的重要组成部分,它直接决定了CINRAD的发射频率和整机的相干性,也是CINRAD整机相位噪声的关键因素。目前,雷达用户往往将频综看作一个黑匣子,只了解频综的输出信号参数,而放弃频综内部的故障定位。文章给出了CINRAD/SB频综的工作原理和框图,再基于频综的工作原理、利用电子设备规范化的维修流程、结合CINRAD/SB的故障现象,列举了CINRAD/SB频综故障定位的几个例子,说明了雷达用户能够对CINRAD/SB频综进行故障定位,希望能为CINRAD/SB频综的排障提供帮助,以提高雷达用户的设备技术保障能力。
The frequency synthesizer is an important part of CINRAD, which decides directly the working frequency of the CINRAD transmitter and the coherence of the whole total CINRAD, and is also a key factor influencing the phase noise in CINRAD. At present, radar users usually think it as a black box： only know its output signal parameters without locating the inter faults. The working principles and the block diagram of integrated generator of CINRAD/SB are explained, based on which, some examples of its fault location are given by making use of the standardized maintenance process of electronic equipment, combined with the radar fault phenomena. The procedures of fault location for radar users are illustrated，so to help radar maintenance personnel improve the capability of equipment technical support.
