MULTI-POSITION RADAR METHOD Russian patent published in 2022 - IPC G01S13/00 G01S13/78 

FIELD: radar technology.

SUBSTANCE: invention relates to radar technology, namely to methods for constructing radar stations (radars) and can be used to build a multi-position radar for various purposes, for example, air traffic control. According to the method, radar signals are emitted and reflected signals are received by the equipment of spaced positions. Object detection, measurement of their coordinates, determination of trajectory parameters are performed. At the same time, the information received from the equipment of the spaced positions is combined and jointly processed at the information processing point, the information received is corrected by comparing the information received from the equipment of different spaced positions. Detection of objects, measurement of their coordinates and determination of trajectory parameters are performed by equipment of spaced positions, which use active phased array antenna arrays (APAA) as antenna systems. To classify air objects, information from the state identification system with APAA and automatic dependent surveillance equipment is used. The receiving-emitting equipment of the spaced positions is placed under a radio-transparent shelter and installed on the hills of the terrain or, if necessary, on towers. Only information about the trajectories of detected objects is transmitted to the information processing point from the equipment of spaced positions.

EFFECT: possibility of viewing the space by electronic scanning of the directivity diagram and improving the spatial selection of detectable objects through the use of active phased antenna arrays.
