发明名称 DEVICE DETERMINING PARAMETERS OF MOVEMENT OF OBJECT
摘要 radiolocation, specifically, processes reconstructing trajectory of target in spaced radiolocation. SUBSTANCE: device includes transmitting position and receiving position in point distant from transmitting position. Receiving position has antenna connected to receiver whose output is linked to inputs of unit measuring Doppler frequency and to inputs of unit measuring direction of arrival of interference signal, unit of extrapolation of measured parameters whose one input is linked to output of unit measuring Doppler frequency, whose second input is connected to output of unit measuring direction of arrival of interference signal and whose output is coupled to input of unit computing moment of time of target crossing line of base, unit determining surfaces of position connected with first input to output of unit computing moment of time of target crossing line of base, with second input to output of unit of extrapolation of measured parameters and with output to one of inputs of unit computing trajectory parameters, another input of it being linked to output of unit measuring direction of arrival of interference. In correspondence with invention there are inserted two units: unit determining statistical characteristics of measurement errors of Doppler frequency and direction of arrival of interference signal and unit of final computation of trajectory parameters One input of unit determining statistical characteristics of measurement errors of Doppler frequency and direction of arrival of interference signal is linked to output of unit measuring direction of arrival of interference signal, its second input is connected to output of unit measuring Doppler frequency and its output is connected to one of four inputs of unit of final computation of trajectory parameters, its other three input being separately linked to outputs of unit measuring direction of arrival of interference signal, unit measuring Doppler frequency and unit computing trajectory parameters. Output of unit of final computation of trajectory parameters is output of device. EFFECT: increased precision in location of position of object. 6 dwg
