Abstract

A new approach to the creation of millimeter-wave radio imaging systems is proposed. This approach is based on the use of an array receiver consisting of a densely packed (pixel size of 4 mm) array of planar mixers located in the focal plane of a quasi-optical objective, with application of the frequency-modulated continuous-wave radar technique. It has been demonstrated that the implementation of the heterodyne type of reception makes it possible to increase the distance range of the array radio imaging system up to ~100 m while maintaining the angular resolution at the previous level.

基于异频探测的阵列无线电成像技术与连续波雷达技术的应用

摘要提出了一种创建毫米波无线电成像系统的新方法。这种方法的基础是使用一个阵列接收器，该接收器由位于准光学物镜焦平面上的密集排列（像素尺寸为 4 毫米）的平面混频器阵列组成，并应用频率调制连续波雷达技术。结果表明，采用外差接收方式可以将阵列无线电成像系统的距离增加到约 100 米，同时将角度分辨率保持在原来的水平上。
