The proposed radar contains a transmitting antenna, a receiving antenna, two mixers, an amplifier, a frequency modulator with a linear characteristic,a control signal former, a frequency synthesizer, a displaying unit, a target identification unit, and additionally, a spectral function former with an adaptive lattice filter. The output of the modulator is connected to the input of the transmitting antenna and the second input of the first mixer. The first input of the control signal former is connected to the output of the modulator. The input of the frequency synthesizer is connected to the second input of the control signal former, and the output is connected to the second input of the second mixer. The first input of the displaying unit is connected to the third output of the control signal former. The target identification unit contains a control unit, a read-only memory unit, a correlator, a threshold unit, and a random-access memory unit. The output of the threshold unit is connected to the second input of the displaying unit, and the second input is connected to the second output of the control unit. The first output of the random-access memory unit is connected to the input of the control unit, and the second output is connected to the second input of the correlator. The first input of the spectral function former is connected to the output of the amplifier, the second input is connected to the third output of the control signal former, and the output is connected to the input of the random-access memory unit and the third input of the displaying unit. The input of the random-access memory unit is used as the input of the target identification unit. The proposed radar is distinctive by its increased resolution and accuracy in operation conditions with transient interferences.
