FIELD: radiolocation. SUBSTANCE: device comprises two Q-channels each incorporating m digital filters connected in series. Signals from them go to m registers. Device also includes adder, code converter counter and envelope detector common for both channels. Inputs of Q-channels are information inputs of device, clock inputs of all digital filters are integrated and connected to recording inputs of registers, counting input of counter and clock input of device. Input of signal of zero range of device is connected to input of counter for zero setting which output is coupled to input of code converter which m outputs are connected to inputs of proper registers for zero setting. Outputs of registers are connected to inputs of adders and outputs of the latter are linked to inputs of envelope detector which output is output of the device. Operation of device is controlled by signals coming from synthesizer of radar. EFFECT: effective detection of phase-shift signals from targets at different ranges including those located inside dead zone, that is of pulse volume of uncompressed phase-shift signal. |
