ABSTRACT:
A radar is provided which has an antenna for transmitting and receiving waves and a transmitting and receiving device for transmitting a signal from the antenna corresponding to reference pulses of a reference pulse generator and receiving with the antenna the reflected signal from a target to generate an intermediate frequency signal. A gate pulse generator under the control of the reference pulses generates gate pulses which determine the sampling position of the intermediate frequency signal. A sampling gate circuit detects a video signal by sampling the intermediate frequency signal from the transmitting and receiving device in accordance with the gate pulses. A display displays the video signal.
