DEVICE FOR DETERMINING MOTION PARAMETERS OF GROUND FACILITIES IN A TWO-POSITION SYSTEM OF SMALL ONBOARD RADARS Russian patent published in 2021 - IPC G01S13/52 G01S13/42 

FIELD: radar.

SUBSTANCE: invention relates to the field of radar and can be used in radars with synthesized antenna aperture. The claimed device contains an onboard radar station made in the form of an antenna system, three receiving units, three processors, three subtraction units, two arc tangent calculators and a calculator of range rate. In this case, a second on-board radar station is additionally introduced into the device, and a inclined range determination unit and a display and information transmission unit, as well as a control and information processing unit containing a series-connected first transmission and reception unit, a calculation unit, are additionally introduced into the device, tangential velocity of the object in the coordinate system of the first OBRLS, unit for calculating the full vector of velocity and direction of movement of the object in the coordinate system of the first OBRLS, unit for calculating the acceleration of the object in the coordinate system of the first OBRLS, the second unit for receiving and transmitting in series, unit for calculating the tangential velocity of the object in the coordinate system of the second OBRLS, unit for calculating the full vector of speed and the direction of movement of the object in the coordinate system of the second OBRLS, a unit for calculating the acceleration of the object in the coordinate system of the second OBRLS.

EFFECT: expanding the functionality and improving the accuracy of determining the trajectory coordinates of objects.
