The requirements for a multi-beam radar receiver used for detecting small-scale low-visible low-speed targets at short range against the background of reflections from the earth’s surface and local objects, are extremely high in terms of providing a large dynamic range for 1 dB of compression, low noise and low power consumption. The present paper is devoted to the solution of the outlined problem in the space of diametrically contradictory parameters, where the problem of structural-parametric synthesis is formulated, methods for optimizing the structure and its elements are considered, and basic algorithms for finding general and particular solutions of the synthesis problem are determined.
