介绍了某型程控多普勒信号源的工作原理,阐述了该信号源的“跳频”故障现象和故障排查、检测、定位的过程,详细分析了产生故障的机理和原因,给出了设计改进的措施,以消除此类故障的干扰.目前该型信号源已大量使用,工作稳定可靠.
The working principle of a type of programmable Doppler signal source is introduced. The phenomenon of “frequency hopping” of the signal source and the process of troubleshooting, detection and positioning are described. The mechanism and cause of the fault are analyzed in detail. To improve the design of measures to eliminate such interference interference.Currently this type of signal source has been extensive use of stable and reliable.
