The emitted radio waves are used for aircraft and other targets.soThe light is reflected and input to the receiver 4 via the radar antenna 1 and the circulator 2. The receiver 4 amplifies and frequency-converts the weak aircraft signal and inputs it to the quantizer 5 as a radar video signal. This signal is converted from an analog signal to a digital signal by the quantizer 5. The radar video signal converted into the digital signal is stored in the input buffer 6 for each sweep, and is written in a predetermined address of the image memory 7 at the timing of the TV signal given by the scan converter 14.
