METHOD OF DETERMINING SPEED OF MOVING OBJECTS USING PASSIVE LOCATION METHOD Russian patent published in 2016 - IPC G01S17/06 H04N7/18 G06T1/00 G06K9/62 

FIELD: radio engineering, communication.

SUBSTANCE: method of determining the speed of moving objects using a passive location method includes obtaining the image of an aircraft using a television system with the generation of video frames of the movement of the moving object in the field of vision of the optical system and digitisation thereof, determining the displacement value of the image of the moving object on a photodetector array based on the displacement of the centre of gravity of the image. The method also includes identifying the type of the moving object and determining the linear dimensions of the object based on the type of the object. Using the displacement value and the ratio of the linear dimensions of the moving object, the linear displacement of the moving object in the field of vision of the optical system L is calculated and the speed of the moving object is determined.

EFFECT: implicit determination of the aircraft speed using passive location means.
