对于机载地球观测应用，人们对重量轻、成本低、高分辨率的成像传感器特别感兴趣。调频连续波（FMCW）技术和合成孔径雷达（SAR）技术的结合可以导致这样的传感器。针对调频连续波信号的特点，提出了一种改进的SAR成像算法。约束的有效性的停止和去近似示出。德尔夫特理工大学已经建立了一个演示系统，并介绍了上一次空降战役的一些结果。
For airborne Earth observation applications, there is a special interest in lightweight, cost effective, imaging sensors of high resolution. The combination of frequency modulated continuous wave (FMCW) technology and synthetic aperture radar (SAR) techniques can lead to such a sensor. In this paper, a developed algorithm for SAR imaging that takes into account the special characteristics of FMCW signals is presented. Constrains for the validity of the stop and go approximation are shown. A demonstrator system has been built at Delft University of Technology and some results from the last airborne campaign are presented.
