Embodiment Construction

[0029] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] The invention discloses an unmanned aerial vehicle automatic tracking antenna feeding system, such as figure 1 , figure 2 As shown, it includes a base 9, a servo turntable 6 is installed on the base 9, and an antenna assembly is arranged on the servo turntable 6. The servo turntable 6 is used to adjust the attitude of the antenna assembly to ensure that the antenna assembly can be carried out according to the position change of the target drone. Tracking and adjustment to achieve signal transmission with the target drone.

[0031] The antenna assembly includes a horn antenna 11, a log-periodic antenna 12, and a helical antenna 13. The initial installation states of the horn antenna 11, the log-periodic antenna 12, and the helical antenna 13 are all horizontal.

[0032] The working frequency band of the horn antenna 11 is 5.725 GHz-5...

Abstract

The invention discloses an automatic tracking antenna feed servo-system of an unmanned aerial vehicle. The system comprises a base. A servo turntable is mounted on the base. An antenna assembly is arranged on the servo turntable. One side or two sides of the servo turntable are provided with high-definition cameras. The high-definition cameras are used for capturing the image of a target unmannedaerial vehicle. The top of the servo turntable is provided with an electronic compass. The base is also provided with a signal input interface, a signal output interface, a control interface and a power supply interface. The signal input interface and the signal output interface are connected with the antenna assembly. The control interface is connected with the servo turntable, the antenna assembly, the high-definition cameras and the electronic compass, and furthermore the control interface is connected with a control unit. The automatic tracking antenna feed servo-system satisfies a requirement of wideband coverage. The automatic tracking antenna feed servo-system has advantages of small size of the whole system, small weight, effective facilitation of mounting and use, simple structure, high convenience in use, simple servo control, easy operation, high stability, and automatic tracking and adjustment.

Description

【Technical field】 [0001] The invention belongs to the technical field of antenna servo automatic tracking, in particular to an unmanned aerial vehicle automatic tracking antenna feed system. 【Background technique】 [0002] In modern electronic equipment, the use of wireless communication technology for wireless transmission of data, sound, images, etc. has been more and more used. Antenna, as a kind of electromagnetic signal transmission, is mainly responsible for target feedback, suppression, interference, countermeasures, imaging and other tasks. The function of the servo system is to process, analyze and track the signal feedback, and it is a necessary device for the application of radio tracking communication. [0003] However, at present, the bandwidth of a single antenna is narrow. Under the requirements of broadband use, it is generally necessary to install at least 6 antennas with different frequency bands, resulting in an increase in the size of the entire system, ...
