%X The asynchronous bistatic SAR imaging issue of variable velocity transceiver is studied in this paper. First of all, the geometric scene of the variable velocity transceiver model is constructed, and the approximation model of the echo of the bistatic SAR is obtained based on the analysis of the instantaneous transceiver distance of the echo. Variable velocity transceiver leads to transceiver position asynchronous, and cause that the SAR data in the azimuth position samples non-uniformly. This paper first analyzes the method with which asynchronous bistatic model equals to monostatic variable velocity motion model. Then with the non-uniform FFT, it resolves the non-uniform sample problems raised by variable velocity motion. The simulation experiments show that the bistatic SAR images have good quality, which verifies the effectiveness of the method provided in this paper.
