DEVICE FOR MEASURING SPEED OF OBJECT Russian patent published in 1995 - IPC

FIELD: measurement engineering. SUBSTANCE: device for measuring the speed of object has time interval meter, object speed computer and radiators and receivers of high-directional sounding radiation connected with them and arranged at the beginning and at the end of metering interval of route. Introduced at the beginning and at the end of metering interval of route in sections locating the flight of object orthogonally to longitudinal axis of route are coordinate axes and beam grids connected with them. Semi-reflecting mirrors are mounted in each section in parallel with coordinate axes in pairs opposite each other on either of longitudinal axis of route. After each mirror N receivers of high-directional sounding radiation are located. Besides that, radiator is located after each engageable pair of mirrors whose sounding beam connects ZN receivers located after semi-reflecting mirrors in the course of reflection and passage through engageable pairs of these mirrors. Outputs of ZN receivers are connected to object speed vector computer through multi-channel meter of output intervals. EFFECT: recording time of fly-by in analog and digital form and coordinates of object at forecast accuracy and determination of magnitude and direction of vector of object speed at measuring interval. 2 dwg
