摘要
极化信息在雷达目标检测和识别中起到越来越重要的作用。射频信号极化模拟技术利用正交双极化宽带天线产生轴比可调、旋向可调、倾角可调的平面波,模拟雷达信号极化特性。极化模拟装置具有本地控制、远程控制、外场数据回放和自动化校准等功能,实现了线极化、圆极化和椭圆极化等高精度、大带宽极化状态的快速模拟,可满足工程应用要求。
Polarization information plays a more and more important role in radar target detection and rec- ognition. Simulation of RF signal polarization technology uses dual polarized broadband antenna to produce axial ratio adjustable, rotation adjustable, angle adjustable plane wave which can simulate radar signal polarization characteristics. RF signal polarization simulator can realize local control, remote control, data playback and automatic calibration. It can realize the simulation of line polarization, circular polarization and elliptical polarization in high accuracy and wide band for engineering application.
