Abstract

Abstract

Benefiting from the combined processing of echo signals received on spatially separated platforms, bistatic spaceborne SAR has many valuable applications such as survey, interferometry, target recognition and classification, disaster monitoring, etc. In order to improve the imaging performance further, this paper presents a bistatic spaceborne Multiple-Input Multiple-Output SAR (MIMO SAR) system combined with Space-Time Coding (STC) and Short-Term Shift-Orthogonal (STSO) chirp waveforms. With the help of digital beamforming techniques on receive, different transmitting waveforms can be separated and extracted from mixed echoes, so that such enhanced architecture can achieve the advantages of both bistatic and MIMO configuration from more spatial degrees of freedom. Furthermore, it offers an opportunity for mitigating the influences of double-bounce scattering by using beamforming on multiple SAR images. The theoretical analysis is derived in detail, then validated by simulation experiments.
