AUTOMATIC INDEPENDENT AIR OBSERVATION SYSTEM IN THE FAR NAVIGATION ZONE Russian patent published in 2018 - IPC G01S3/46 

FIELD: radar ranging and radio navigation.

SUBSTANCE: invention relates to the passive radar ranging methods and systems, and can be used for the aircraft (AC) (aircraft, helicopter, etc.) located radio frequency source (RFS) location in the three-dimensional space, due to the generated by this RFS electromagnetic waves reception and subsequent processing. Automatic independent air surveillance system in the far navigation zone contains N receiving antennas, the first and the second analog-to-digital converters, computer, intended for the operating modes setting and performing the received signals preliminary digital processing and their compression, low-noise amplifier, the first and second multi-channel synchronous quadrature receivers, first and second information processing channels, control controller, diagram-forming device, the radio modems unit, fiber-optic communication line, output signal generation device; transmitting phased array antenna, local data transmission system, communication manager software, where the measurement information accumulation takes place and the optimal communication with the local data transmission network decision is made, at that, the listed means are connected to each other in a certain way.

EFFECT: coordinate readings digital path generation in the form of the AC flight path interactive display.
