SIGNAL PROCESSING DEVICE Russian patent published in 2004 - IPC

FIELD: passive detection and ranging.

SUBSTANCE: the device has a corrected constant read-out unit, azimuth and azimuth marks transmitter, direction-control switch, coincidence element unit, secondary processing unit and a second subtracter, a separate output and a group of outputs of the azimuth and azimuth marks transmitter are respectively connected to the separate inputs of the secondary processing unit, corrected constant read-out unit, and to the group of inputs of the coincidence element unit, having a separate input connected to the output of the direction-control switch, whose first and second of the first signal transmitter and to the output of the second signal transmitter, and the group of outputs of the coincidence element unit is connected to the first group of inputs of the secondary processing unit, whose second group of inputs is connected to the group of outputs of the measuring device also connected to the second group of inputs of the second subtracter, having the first group of inputs and a group of outputs respectively connected to the group of outputs of the secondary processing unit and to the second group of inputs of the subtracter, whose first group of inputs is connected to the group of outputs of the corrected constant read-out unit.

EFFECT: enhanced accuracy of determination of the range to a moving radiator.
