摘要

本文介绍了噪声雷达技术在x波段窄带地面合成孔径雷达(GB)中的实现结果。所考虑的雷达以噪声波形(NW)作为探测信号，通过将雷达回波与传输前的参考信号相关联来进行距离聚焦，而方位角压缩的方式与传统SAR相似。根据获得的干涉图，对GB NW SAR的相位测量精度进行了评估。研究表明，两种NW SAR系统都能提供相当高的位移测量精度。研究还表明，噪声雷达技术可以为具有干涉测量能力的短程应用(包括地基SAR和d-InSAR系统)提供相当高性能的雷达。

Implementation of Noise Radar Technology in Ground Based SAR for Short Range Applications

In this paper, results of implementation of noise radar technology in X-band narrowband ground based (GB) synthetic aperture radar (SAR) were presented. The radars under consideration use noise waveform (NW) as a probe signal and perform the range focusing by correlating the radar returns with a reference signal taken before transmission, while the way the azimuth compression is done is similar to that of the conventional SAR. Evaluation of the phase measurements precision with the help of GB NW SAR was carried out on the basis of the obtained interferograms. It has been shown that both NW SAR systems provide quite high precision of displacement measurements.It was also demonstrated that noise radar technology may provide rather high performance of radar designed for short range applications with interferometric capabilities including ground based SAR and d-InSAR systems.
