An aircraft antenna beam selection controller

Abstract

An aircraft antenna beam selection controller is installed on an aircraft, and a relation model of an angle of a target point relative to an antenna coordinate system and beam performance is preset inthe aircraft antenna beam selection controller; before the aircraft takes off, longitude and latitude height information, a take-off point and take-off direction information of a communication targetpoint are bound; in the flight process of the aircraft, flight parameter data are received in real time, the angle of the communication target point relative to the antenna is calculated through theinformation, the angle is substituted into the relation model of the angle of the target point relative to the antenna coordinate system and the beam performance, and an optimal beam is selected; andthe beam selection controller uses the selected optimal beam to receive and transmit data through the IO control antenna to realize data communication between the aircraft and the target point. According to the controller, high-efficiency and high-dynamic communication can be realized in a low-cost manner.

Description

technical field [0001] The invention relates to an aircraft antenna beam selection controller, which belongs to the field of measurement and control communication. Background technique [0002] In the past, aircraft antennas mostly used fixed beams to communicate with the target point, and the selection and control of the antenna beam could not be realized. However, the flight attitude is changing all the time, and its relative position with the target point is also changing in real time. The communication performance of the fixed beam antenna will be affected. impact to a great extent. The new-generation phased array beam steering method has problems such as large size, high power consumption, high cost, poor reliability and maintainability. Therefore, how to realize high-efficiency and high-dynamic communication in a low-cost manner has become a problem to be solved. Contents of the invention [0003] The technical problem of the present invention is: to overcome the d...
