一种新型车载雷达天线舱开合系统的设计

Design of Antenna Cabin Open-Close System for Vehicle-Borne Radar

摘要:

车载雷达广泛应用于民用和军事领域,其天线舱对雷达具有良好的保护作用。针对目前基于继电器控制的开环车载雷达天线舱开合系统存在的问题,设计了一种基于STM32微处理器,并采用直线位移传感器和PID算法的低成本、高可靠性的闭环车载雷达天线舱开合系统,解决了在传统的基于继电器控制电动推杆的开合系统中,电动推杆容易损坏、天线舱容易变形等问题。新型车载雷达天线舱开合系统在实际工作的过程中,具有开、合速度快,运行平稳等特点,且左、右电动推杆的行程误差小于1mm。

Abstract:

The vehicle-borne radar is widely used in civilian and military fields, and its cabin has good protection for the radar. The problems existing in the open-close system of the traditional vehicle-borne radar antenna cabin controlled by relay are described in this paper, and a new kind of low-cost and high-reliability vehicle-borne radar antenna cabin roof open-close system based on the STM32 microcontroller, PID algorithm and the linear displacementSsensor was designed to solve the faults of the traditional vehicle-borne radar antenna cabin open-close system, which is easy to get damaged. The open-close system of the new vehicle-mounted radar antenna module is stable in operation, and the left and right electric actuator stroke error is less than 1mm.
