SYSTEM FOR DETERMINING COORDINATES OF TARGET Russian patent published in 2021 - IPC G01S13/74 G01S13/78 

FIELD: physics.

SUBSTANCE: invention relates to radar ranging, as well as aircraft engineering, in particular to variation of wing curvature by slats and flaps, to control and transmission systems to actuate control surfaces, slats and flaps, and to digital computing and processing devices specifically designed for specific functions, and can be used in secondary radar systems when determining coordinates of a target in a request-response system. System for determining coordinates of a target, placed on a carrier, includes an antenna directed to a target, a request-response system placed on the carrier mobile part of the carrier, configured to match target position parameters, carrier position and antenna aiming direction to determine target location, digital computing device for calculating target coordinates at any position of carrier and antenna on carrier, height sensor and sensors of angular position of carrier. Digital computing device of the system further includes a unit for calculating the current angular coordinate, said module comprises in-series connected communication module with input signals, reaction calculation module and angular position output module. Reaction calculation module is configured to calculate the current angular position of the mobile component of the carrier, which is received as the current angular position of the antenna. Angular position output module is configured to output the calculated values of the current angular position of the movable component to the digital computing device of the system for determining coordinates of the target and to external systems of the carrier, if necessary.

EFFECT: technical result consists in determination by system for determination of coordinates of target value of current angular position of movable component of carrier (aircraft) and installed on it antenna in real time, using current values of control signals of mobile component, as well as in possibility of using system on carriers, for which obtaining information on angular position of their movable component parts is impossible.
