某型无人机载雷达的结构设计

Structure Design of an Unmanned Aerial Vehicle Radar

无人机具有研制成本低、环境适应能力强等优势,广泛应用在民用和军用上,但无人机体积较小,研制高可靠性的小型化和轻型化无人机载雷达难度较大。文中论述了某无人机载雷达结构设计的总体方案,利用功率射频单元与天线单元结构一体化和环控一体化设计,实现了无人机载雷达的小型化和轻型化设计,并通过力学仿真和热仿真验证了该方案的可行性。该设计方案成功解决了无人机载雷达占用空间小、重量要求苛刻及无人机无法提供液冷源等技术难题,可供今后同种类型无人机载雷达的结构设计参考。

The unmanned aerial vehicle （UAV） is widely used both in civilian and military domain because of its advantages both in cost of research ＆ manufacturing and environmental adaptability. It is difficult to research and manufacture the smaller and lighter unmanned aerial vehicle radar with high reliability due to the small space of UAV. In this paper an advanced scheme for the structure design of UAV radar is presented and verified by mechanical simulation and thermal simulation. The UAV radar with small size and light weight is achieved through structure integration design and thermal integration design of low-power radio frequency unit and antenna unit. This scheme can successfully solve the difficult problems such as small space and extremely limited weight of the UAV radar and no cooling source from UAV and so on. It can provide good reference for further structure design of the similar UAV radar.
