Phased Array Antenna Beam Steering Device

Abstract

A phased array antenna beam control device disclosed in the present invention aims to provide a beam control device with low power consumption, small size, high reliability, scalability, and strong versatility. The present invention is realized through the following technical solutions : n loop connectors are interconnected through sub-cards, fixedly connected to the adapter board to connect the TR component control interface, power interface and terminal control interface, and 1-n signal processing sub-boards are respectively fixed on 1-n loops In the loop-shaped hollow area of ​​the connector, the signal processing sub-board is embedded in the loop-shaped connector; the adapter base board matches the phased array antenna of different platforms through the TR component control interface, and the selected signal processing sub-board controls the interface and status through the TR component The monitoring interface receives the communication command from the end machine of the beam control system, analyzes the communication command and calculates the wave bit code, and outputs the control timing to the loop connector, and the loop connector fan-outs the control signal pins of the signal processing sub-board through the adapter board To the TR component that needs to be controlled.

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, which is widely used in the fields of measurement and control, communication, etc., uses an array antenna composed of multiple 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 M...
