Radio signal power calculation at active homing head receiver's the output is carried out. This can be done by half-nature and imitating simulation of the active homing head in the structure of homing system of an aircraft. Signal power calculation takes into account influence of the active homing head antenna directivity diagram, the target backscattering diagram, reflected circular polarized signal depolarization. Imitation of the radar signal reflected from the target is carried out by a method of the elementary components, when a complex target is replaced with a set of elementary forms (a sphere, a cone, a flat rectangular plate, a flat triangular plate).
