Abstract:

An equivalent monostatic model is first established for the traditional OmegaK imaging algorithm being to be applied to the bistatic synthetic aperture radar (SAR). Then, based on the equivalent monostatic SAR, a twodimensional spectrum model is further established. In fact, the traditional OmegaK imaging algorithm can cause the loss of echo information, so the optimal focusing effect can not be approached. Therefore, a kind of new OmegaK imaging mathematical model is proposed in order to make full use of all echo information and effectively improve the focusing performance. Finally, the experimental results show that the abovementioned methods are valid and feasible.
