On the basis of the existing algorithms for processing of radar signals using the methods of solving ill-posed problems and the analysis has been suggested that the problem of reduction in the definition of the regularized solutions is promising and will allow semi-chit increase in accuracy (resolution) noise immunity is at least two times in comparison with existing processing techniques. Three variants of an inverse ill-posed problem and methods of its regularization (such as Tikhonov regularization method, Kalman filter, and so on) with respect to the radar. Analyzed and studied example of regularized solutions for the Fourier transform, which is built on the basis of a decision of the Fredholm integral control of the first kind of convolution type, which is used for mathematical processing of signals in radar, navigation and other fields.
