GEAR DETERMINING PARAMETERS OF MOVING TARGET Russian patent published in 1998 - IPC

FIELD: radiolocation, methods reconstructing trajectory of target in diversity radars. SUBSTANCE: gear taken as prototype has transmitting position, receiving position located in point distant from it and including antenna connected to receiver which output is linked to inputs of unit measuring direction of arrival of interference signal and to inputs of unit measuring Doppler frequency, unit determining surfaces of position which output is connected to one of inputs of unit computing trajectory parameters which other input is connected to output of unit measuring direction of arrival of interference signal and which output is output of whole gear. Gear is inserted with two new units: unit of extrapolation of measured parameters and unit computing time moment of crossing of base line by target. One of inputs of unit of extrapolation of measured parameters is connected to output of unit measuring direction of arrival of interference signal and another input of it is linked to unit measuring Doppler frequency. Output of unit of extrapolation of measured parameters is connected to input of unit computing time moment of crossing of base line by target and to one of inputs of unit determining surfaces of position which other input is linked to output of unit computing time moment of crossing of base line by target. EFFECT: possibility of determination of position of target before it crosses base line ( line connecting phase centers of antennas of transmitting and receiving positions ). 5 dwg
