DEVICE FOR DETERMINING MOTION PARAMETERS OF TARGET Russian patent published in 2016 - IPC G01S3/00 

FIELD: radar and radio navigation.

SUBSTANCE: said result is achieved by the fact that the device has a transmitting position, consisting of series-connected the transmitter and antenna, and in remote from the point of the receiving position, which consists of the antenna receiving position with N outputs, each of which, except the central, is connected to one of the inputs of respective adder output is connected to the input of the corresponding receiver, and central output of the antenna is connected to the input of reference voltage divider with N outputs of corresponding to the output of which is connected directly to the input of receiver central partial channel, and other N-1 outputs are connected to second inputs of adders corresponding partial channels, also includes a unit for determining the azimuthal position of antenna directivity diagram transmitting position with its input connected to the second output of the receiver Central partial channel, and output is connected to the second input of computing unit of trajectory parameters, the transmitter transmitting position comprises a synchronisation unit , frequency synthesiser, a power amplifier and beam control unit connected to each other in a certain manner, outputs of the receiver of each of the partial channels separately are connected to corresponding inputs of the unit of measurement of direction of arrival of the interference signal, the output of which is connected to the first input of computing unit of trajectory parameters, also includes series-connected unit for measuring the Doppler frequency, a unit of extrapolation of measured parameters (dependencies of Doppler frequency and angular direction of the target in time), unit for calculating the moment of intersection to line base and a unit for determining surface position, the output of which is connected to the third input of computing unit of trajectory parameters, as well as target altitude calculation unit, connected with other units of the disclosed device in a certain manner.

EFFECT: enabling determination of flight altitude of the target at wide beam pattern of the receiving antenna in vertical plane.
