The methods of obtaining of an image of radar objects with the improved angular resolution are offered rather simple for practical realization. On the basis of the preliminary information on a source of signals algorithms allow to increase consistently the effective angular resolution before achievement greatest possible for a solved problem. Algorithms of secondary processing of the information necessary for it are described. Adequacy and stability of the received decisions is investigated on the created mathematical model. The created high-speed algorithms allow to process signals in a of real time mode. Methods of the further increase of effective angular resolution of systems on the basis of more complex algorithms of data processing are developed. The opportunity of increase in the effective angular resolution is shown at much smaller signal to noise ratio, than at use of known methods.
