METHOD FOR SPACE SURVEILLANCE BY RADAR STATIONS WITH PHASED ANTENNA ARRAYS Russian patent published in 2018 - IPC G01S13/02 

FIELD: radio engineering, communication.

SUBSTANCE: space surveillance is based on cooperation of radar stations distanced in space with phased antenna arrays (PAA). In the surveillance process the radar stations exchange information on noise environment measured in each angular direction of the surveillance zone. In angular directions, in which detection of targets at required range is provided, space surveillance is carried out by a single-way radar station with phased array providing minimum energy costs. The angular directions in which a jammer is operating, the space surveillance is carried out by the radar stations distanced in space with the phased antenna array in passive operation mode. In this case, the coordinates of radar stations with the phased antenna array are clarified and the jamming coordinates are provided to a common information system. In angular directions with "impassable" noise interference power, in which the density of the jamming power flow does not provide detection of the target at required range the space surveillance is carried out by spaced radar stations. The active radar station makes it possible to detect an air object at maximum range under conditions of active noise interference effect. The area of space where detection of the air objects under the active noise interference effect by the one-way radar station is impossible, scanning is performed by the radar station operating in the passive mode. At that one bistatic radar station is selected to provide surveillance for maximum number of resolution elements with specified detection quality but not exceeding the allocated energy resource.

EFFECT: maintain operation range of the radar stations with phased antenna arrays under the active noise interference effect with limited energy costs for area surveillance.
