Bistatic Synthetic Aperture Radar imagery simulation of sea surface

A bistatic Synthetic Aperture Radar (Bis-SAR) imagery simulation of an extended sea surface is presented which is based on a facet scattering model. A semi-deterministic approach is developed to calculate high frequency bistatic raw data from the model of large sea surface. An effective method of modified nonlinear chirp scaling (NLCS) algorithm is presented to handle a general case of bistatic raw data and generate the simulation imagery of sea surface. This algorithm solves the inefficient problem for some time-domain algorithms and extends the limited number of bistatic cases to general for some frequency-domain methods. The concrete models and imagery results are illustrated.
