摘要

合成孔径雷达(SAR)原理的发明可以追溯到20世纪50年代初。其基本思想是对侧视雷达中的目标进行方位上的多普勒滤波，距离上的脉冲或调频调制压缩。自从这个时候SAR系统已经，从技术的角度来看，相当细化到最先进的分辨率和精度接近理论极限的状态。本文提出了一种新的单频SAR系统思想，通过相位比较来实现分辨率。系统配置变得非常简单，适用于地面和机载高分辨率SAR。

New SAR system configuration for detection of buried objects

The invention of the synthetic aperture radar (SAR) principle dates back to the early 1950s. The basic idea is to filter targets in a side looking radar according to their Doppler history in azimuth and by pulse or FM modulation compression in range. Since this time SAR systems have been, from a technical point of view, considerably refined to the state of the art where resolution and accuracy are close to the theoretical limits. This paper presents a new system idea for a single frequency SAR, where resolution is achieved by phase comparison. The system configuration becomes extremely simple and is suited for groundbased and airborne high resolution SAR.
