Abstract：In order to help radar support professionals gain a deeper understanding of the generation,measurement,and trou-bleshooting of radar local oscillator signals,this article adopts a top-down modular design method and an architecture of upper com-puter+microcontroller+phase-locked loop(PLL)frequency synthesis module+power control module to develop a low-cost and sim-ple radar local oscillator signal generation platform.The upper computer of the platform controls the microcontroller through USB communication,and then controls the PLL frequency synthesis module to generate radar first and second local oscillator signals,with flexible and variable parameters such as frequency and power.Then,through a one to two power divider,one is sent to the up frequency conversion branch and the other is sent to the down frequency conversion branch.The radar local oscillator signals generat-ed by the platform have multiple types and stable performance.The upper computer interface is friendly,beautiful,and is easy to operate,making it very convenient for training and skill assessment,and has strong practicality and scalability.
