Focusing General Bistatic SAR Using Analytically Computed Point Target Spectrum
This paper presents a method to compute the twodimensional point target spectrum for the arbitrary bistatic configuration, when transmitter and receiver move along nonparallel tracks with unequal velocities. The point target response is first modeled in the time domain and then transformed to the frequency domain. Based on the bistatic geometry and the method of stationary phase, an analytic expression for the bistatic point target specturm is derived. Using the derived spectrum, focusing for general bistatic SAR configuration can be accomplished by matched filtering. Finally, the proposed approach is verified with a point target simulation.
