A bistatic synthetic aperture radar (Bis-SAR) imagery simulation of an extended maritime scene is presented. An efficient facet scattering model is developed to collect the raw coupling scattering data from a ship located on sea surface. Then, to avoid the inefficiency of time-domain algorithms and the azimuth-invariant limit of conventional frequency-domain (FD) methods in the bistatic case, an extended...
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...
Three-dimensional imaging of sonar has important application in the fields of precise navigation and target recognition. In the paper, we describe an efficient model to compute the backscattering sound of high-frequency from complex underwater target for simulating the 3D image based on sidescan sonar. The target we used is the Generic submarine model which was designed by German FWG workshop. The...
