MONO-PULSE PHASE DEVICE FOR AUTOMATIC DIRECTION TRACKING Russian patent published in 2009 - IPC G01S3/14 

FIELD: physics.

SUBSTANCE: device contains an antenna system, multi-channel mono-pulse receiving device (MRD), first, second and third entrances which are connected respectively to the first, second and third exits of the antenna systems; three circuits connected in series to signal conditioner of errors (SCE) and antenna control unit (ACU). Exits of the first, second and third ACU are connected accordingly with the first, second and third antenna input system. The first inputs of the first, second and third SCE connected accordingly to the first second and third ACU exits, and the second inputs of the first, second and third SCE connected accordingly with the second third and first ACU exits. Antenna system is made of three adjacent to each other regions of antenna elements, phase centres which are placed on the apexes of equilateral triangles, positioned in an aperture plane of the antenna system, and one of the sides of the triangle is parallel to the azimuth plane, and the outlets of the phase centres are in correspondence with the outlets of the antenna system.

EFFECT: increase in precision of the automatic tracking of the locating object by direction in conditions of low signal-to-noise ratio.
