摘　　要：介绍了机载毫米波成像微波辐射计天线扫描系统的工作原理和控制电机的选择与天线配重问题。天线扫描系统采用主从式双计算机结构及零位检测装置，提高扫描精度；驱动装置选用步距角小，精度高的步进电机，简化系统，操作简便灵活；采用偏离转轴的配重措施，克服失步现象，提高了扫描精度。The basis of airborne millimeter wave imaging microwave radiometer antenna scanning system, the selection of controlling motor and the balancing weight of antenna are introduced. The scanning accuracy is improved by adopting structures of master slave computer and zero detecting. The system is simplified and easy to be controlled by selecting a small step angle and high precision step by step motor. It also overcomes the problem of step displacement by adopting balancing weight measure of deviate spindle set and therefore increases the scanning precision.
