The invention discloses an ultra-wide-band lightweight unmanned aerial vehicle airborne direction finding array, and belongs to the technical field of radio direction finding. The direction finding array comprises an antenna array pod body, an antenna array, a switch array and a supporting structure. The pod body is composed of an upper cover and a lower cover, and the upper cover is in threaded connection with the switch array through a connecting stud, so that the switch array becomes a part of the structure of the pod body, the common bearing effect is achieved, and the weight of the pod body is reduced; and the antenna array sequentially comprises a low-section antenna array, a middle-section antenna array, a high-section antenna array and a monitoring antenna unit from top to bottom. According to the invention, the light weight required by an airborne platform is met, and meanwhile, accurate direction finding of signals in an ultra-wide-band of 30 MHz to 18 GHz can be realized.
本发明公开了一种超宽带轻量化无人机机载测向阵,属于无线电测向技术领域。该测向阵包括天线阵吊舱舱体、天线阵、开关阵及支撑结构。吊舱舱体由上罩与下罩组成,上罩与开关阵通过连接螺柱进行螺接,使开关阵成为舱体结构的一部分,达到共同承重作用,以减轻舱体重量;天线阵自上而下依次为:低段天线阵、中段天线阵、高段天线阵以及监测天线单元。本发明在满足机载平台所要求轻量化的同时,可实现30MHz~18GHz超宽频带内信号的准确测向。
