Abstract

In this algorithm the high range resolution is obtained by pulse compression. In azimuth direction the scatter centre distribution is estimated by inverse scattering method, and then the receiving signal of the virtual line antenna array is obtained. High azimuth resolution can be obtained through processing this receiving signal by FFT and high elevation resolution can also be obtained by using FFT according to ISAR theory. Combining range-azimuth image and range-elevation image the three dimensional image can be obtained then. The algorithm presented is approved to be effective through both simulations and experiments.

Key words： millimeter wave radar; SAR; forward-looking three-dimensional imaging
