FIELD: multi-position semi-active radio systems for detecting moving air objects.
SUBSTANCE: surveillance system that implements the claimed method consists of one transceiver radio station and two radio receivers with antenna arrays that receive reflection signals from several moving air objects at specified range boundaries. The method can be used in existing semi-active or active moving object direction finding systems.
EFFECT: creating a method that makes it possible to determine the relative position of the receivers and the transmitter, to detect several objects in the controlled area with finding their spatial coordinates and velocity vectors, and also to increase the Doppler frequency resolution due to the coordinated operation of the transceiver station and two auxiliary receivers.
