数字技术在船用频率捷变雷达信标中的应用

Application of Digital Technique in Marine Agile Radar Beacon

数字技术正渗透到一切电子设计部门,特别是雷达领域。本文叙述了数字技术在频率捷变雷达信标中的应用,它可克服模拟电路的局限性,特别是采用微处理机后,拓展了增强雷达信标功能的途径,如旁瓣的有效抑制、信标机状态的自检及性能自测并遥报、信标机的非实时应答响应、电源的自动搜索控制等。

Digital technique is now infiltrating to all the electronic products, especially in the field of radar. This paper expounds the application of digital technique in the agile radar beacon, which overcomes the limitation of analogue circuit. The following functions of radar beacon is especially improved when microcomputer is adopted: efficiently suppressing of fide lobe, self-detection and remote alarm of beacon state, non-real-time response of the beacon, automatic searching control of power etc.
