Abstract In this paper, the temporol-spatial coupling problem about antenna radiating and receiving of impulse signal SAR is analysed. Using back projection method, an impulse signal SAR imaging algorithm, antenna size how affects the impulse signal SAR azimuth accumulation is analysed in time-domain, the quantificational relation between azimuth accumulation and antenna size is presented. Finally, some usable conclusions about designing ultrawide band SAR antenna and selecting the parameter of transmitting are given.
