Phased array antenna beam control device

Abstract

The invention discloses a phased array antenna beam control device and aims to provide a phased array antenna beam control device which is low in power consumption, small in size, high in reliability,good in expandability and strong in universality. According to the technical scheme, the beam control device is realized through the following technical scheme: n doughnut shape-like connectors are interconnected through sub-cards, fixedly connected onto an adaptive bottom plate and connected with a TR module control interface, a power interface and an end machine control interface; 1-n signal processing sub-boards are respectively fixed inside the doughnut shape-like hollow-out areas of 1-n doughnut shape-like connectors so as to form a signal processing sub-board embedded doughnut shape-like connector; the adaptive bottom plate is matched with the phased array antennas of different platforms through the TR module control interface; a selected signal processing sub-board receives a communication instruction from a beam control system end computer by means of the TR module control interface and the state monitoring interface; the communication instruction is analyzed and a wave position code is calculated; a control time sequence is outputted to the doughnut shape-like connector; the doughnut shape-like connector fans out the control signal pin of the signal processing sub-board to a TR module which needs to be controlled through the adaptive bottom plate.

Description

technical field [0001] The invention relates to the fields of measurement and control, communication and the like, in particular to a phased array antenna beam control device. Background technique [0002] At present, the phased array radar widely used in the fields of measurement and control, communication, etc., adopts an array antenna composed of a plurality of antenna units (radiators), and each antenna unit has a phase shifter. Beam steering systems are an integral part of phased array radars. The main function of the wave control system is to control the direction change of the phased array antenna beam. Its antennas are arranged according to certain rules, and the antennas are controlled by phase shifters to complete directional scanning. In addition to the phase shifter, each unit of the phased array antenna system also includes three parts: the antenna array, the radio frequency transceiver component and the beam control system. The number of antenna units is MN,...
