Abstract
This paper presents an alternating way of processing ASAR IM mode data based on approximate Omega-K algorithm. This algorithm is quite efficient because the interpolation is avoided and only two phase multiplications are required in addition to necessary FFT operations. The errors introduced by the approximation are analyzed based on the ASAR parameters. At last, the simulated point target and ASAR data are used to verify the algorithm. The experimental results show the ASAR data can be well focused
