  • By the method of stationary phase and the concept of HQBA (Half Quasi-Bistatic Angle), an exact two-dimensional spectrum of translational-invariant bistatic SAR is derived in this paper. Based on the analysis of every exponential term in the expanded spectrum, a flow chart of Range-Doppler algorithm with the computation of HQBA is proposed. Simulation results of HQBA, RCM and focused points are also provided. As they show, the proposed method can correct the RCM accurately, and improve the imaging quality.
