Abstract

Abstract: The absence of real downward-looking array SAR system has brought difficulties to data acquisition and further technical for this technology, so the research of downward-looking array SAR 3D simulation has great significance. In order to effectively reflect the 3D imaging advantages of the downward-looking array SAR technology in urban buildings, SIMO and MIMO were used to simulate the downward-looking array SAR echo data of urban buildings in this paper. And then the 3D RD imaging algorithm is processed on the echo data of this two modes. The difference contrast of simulation results of SIMO mode and MIMO mode with original terrain verified the effectiveness of this method and advantages and disadvantages of two models.

Key words: single-input multiple-output (SIMO), multiple-input multiple-output (MIMO), downward-looking array SAR, urban buildings, simulation
