Abstract :
In this paper, the application of spline-models for SAR image reconstruction is proposed. Some complexities of using traditional methods in the case of front-side-looking radar are proved. Knowing antenna pattern and some sounding scheme, features surface image can be calculated. The problem is solved in the class of two-dimensional spline-function for regularization of ill-posed inverse problem. In the paper the problem is modeled for certain conditions, such as antenna angle 45 degrees. Different received and reconstructed signals are modeled for the given conditions.
