Problems solved by technology

[0002] At present, the commonly used direction finding arrays are mainly divided into fixed and mobile. The fixed radio direction finding system has no special requirements on the weight because it is fixed at a certain place. The mobile direction finding antenna array is often erected on a vehicle platform or a large Aircraft airborne platform, there is no urgent need for the weight of the direction finding antenna

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of radio direction finding, in particular to an ultra-wideband lightweight UAV airborne direction finding array. Background technique [0002] At present, the commonly used direction finding arrays are mainly divided into fixed and mobile. The fixed radio direction finding system has no special requirements on the weight because it is fixed at a certain place. The mobile direction finding antenna array is often erected on a vehicle platform or a large Aircraft airborne platform, there is no urgent demand for the weight of the direction finding antenna. When the direction-finding antenna is applied to the UAV platform, in order to ensure its endurance, the integrated and lightweight design of the direction-finding array is particularly important. The wider the working bandwidth, the better. Contents of the invention [0003] In view of this, the present invention provides an ultra-broadband lightweight un...
