Front-side-looking SAR imaging

In this paper, the application of spline -models for some imaging tasks is proposed. Using traditional methods in the case of front-side-looking radar can be very complicated. To calculate surface image antenna pattern and some sounding scheme features should be known. This task is incorrectly formulated inverse problem. The problem is solved in the class of two-dimensional spline-function for regularization. In the paper the problem is modeled for certain conditions, such as antenna angle 45 degrees. For the given conditions, different received and reconstructed signals are modeled.
