摘要
针对现有雷达天线高度不够、运动机构与控制系统配合协调性较差、撤收和展开速度较慢以及折叠后装载适配性较差等问题,提出一种适用于低空飞行目标探测的大型自控型雷达天线。设计了雷达天线的俯仰机构、主塔举升机构等主要运动机构并对其作了运动学仿真分析。仿真结果表明,雷达天线的主要运动机构运动平稳且没有冲击,确保了雷达天线运动的平稳性和可靠性。
Radar antenna are essential for accurately detecting low-altitude flying targets.Addressing issues such as poor coordination between moving mechanism and control systems,and slow deployment speed,this paper proposes a design for a large automatic radar antenna suitable for low altitude target detection.The pitching mechanisms and main tower lifting mechanism are designed,and their kinematic simulations ensure stable and reliable antenna motion.The design features a large antenna array aperture,high height,excellent detection performance,compact size when retracted,rapid deployment,and strong load adaptability.
