A Polarization Twisted Active Angle Reflection Direction Backtracking System

Abstract

The invention discloses a polarization-twisted active angular reflection direction retrospective system, which consists of an active polarization-twisted antenna array, a first polarization selection surface, and a second polarization selection surface that are orthogonal to each other and spliced ​​together to form a trihedral angle reflector . The present invention uses the active polarization twisted antenna array and the specular reflection of the polarization selective surface to realize the direction backtracking and polarization twist of the microwave signal, so as to improve the isolation between sending and receiving; in addition, the active characteristics of the polarization twisted antenna array can be used according to According to the requirements of the application environment, the power amplification of the traceback signal is realized. The invention is applicable to the fields of radar, microwave power transmission, satellite communication, etc., has the characteristics of high transceiver isolation, controllable echo power, etc., has a simple design process, and can be mass-produced by using printed circuit technology.

Description

Technical field [0001] The invention belongs to antenna strainer, specifically a polarization torsional active angle reflection direction retracting system. Background technique [0002] Directional backtrack array has the characteristics of automatic tracking direction without the need for complex signal processing equipment, with large application prospects in the fields of radar, wireless communication, microwave energy transmission. At present, there is three ways to retrore the direction of the direction of the direction, the phase conjugate array (PON array), and the corner reflector, where the VAN ATTA array is used to achieve the phase conjugate, the disadvantage is that the desaction is equal to the electrical network design. More complicated; the PON array can be traced, but a large amount of mixer and vibration feed network are required, the cost is higher; the angle reflector is more passive system, working in a single polarization mode and echo power Low, not satisfy...

AI Technical Summary

Problems solved by technology

At present, there are mainly three ways to realize direction backtracking: Van Atta array, phase conjugate array (PON array) and corner reflector. Among them, Van Atta array uses space conjugation to realize phase conjugation, and its disadvantage is that the equal-length feed network design It is more complex; the PON array can be traced back to a wide range of angles, but requires a large number of mixers and local oscillator feed networks, and the cost is high; corner reflectors are mostly passive systems, working in a single polarization mode and the echo power Low, unable to meet the application requirements for multi-function, high transceiver isolation, and long-distance transmission in radar, communication, and wireless energy transmission systems
