摘要：

The problem of algorithm synthesis for processing of the signals at the output of a spatially distributed antenna system for the formation of radio images from aerospace carriers has been solved. In order to synthesize the optimal algorithm, the maximum likelihood method was used. As a result of analyzing the physical nature of the signal processing operations, a transition to the quasi-optimal processing, which simplifies the technical implementation of the algorithm, is proposed. The main feature of this algorithm lies in the fact is that it allows to receive a radio image in the direction of the nadir within the range of angles that is currently not visible by the radars from aerospace carriers. In this range of angles, an image is usually formed by optical means. A scheme of the radar complex has been developed and modeling of radio image formation has been carried out in accordance with the algorithm.
