微波透镜成像技术在目标识别中的应用研究

摘要

The microwave lens imaging technique in target identification is studied. A new type of radar based on the principle of telescope is given. It＇ s hopeful that microwave lens imaging technique can increase the transverse range resolution. The three-dimensional images with radial distance images for target identification are obtained. Imaging algorithm of microwave lens is studied in order to depress the influence of microwave diffraction and the imaging efficiency is proved by computer emulation results.%研究了微波透镜成像技术及其在目标识别中的应用。提出基于望远镜原理的新体制雷达，实现雷达目标的横向距离高分辨，结合高精度跟踪雷达现有的径向距离高分辨，进行雷达目标三维识别的新概念。此外，针对微波频段的电磁波绕射、衍射效应严重，微波透镜成像效果较差的问题，提出了虚拟透镜成像技术，并进行了成像验证，获得较好的成像效果。
