Research of VCO Phase-Locked Frequency Source Flickering Clutters Caused by Changes in Temperature
摘要
In the spacecraft high-speed data transmission system, for the VCO affected by high and low temperature environment, flickering clutters may occur during the temperature change. Based on this phenomenon, the author gives a test method, followed by the simulation analysis to give the causes. Furthermore, the optimization scheme and simulation analysis results are proposed and passed the physical test. The optimization scheme is found to be effective, which provides a reference solution and basis for the mitigation of flickering clutters.
