Abstract:

At present, the sampling interval of the spacecraft multichannel RF spectrum monitoring system is too long, which results in a large difference between the monitoring results and the actual results. In order to solve these problems, a new spacecraft multi-channel radio frequency spectrum monitoring system based on force position cooperative control was designed, and the hardware and software of the monitoring system were designed. In the use interface of the spectrum analyzer, there are a large number of RF signal control commands, including some interface commands, through which the spectrum analyzer is monitored and controlled. MCU comes with a controller to assist the control unit of the system to control the spectrum; The core of the drive interface circuit in the control unit is 76JG632 chip, which mainly supplies power to various interfaces in the microcontroller. Through the multi-channel RF signal spectrum switching, multi-channel RF signal spectrum display, RF signal spectrum monitoring to achieve the software flow. The experimental results show that the spacecraft multi-channel radio frequency spectrum monitoring system based on force position cooperative control can effectively shorten the sampling interval time and ensure the monitoring results are consistent with the actual results.
