理器。A poor reference oscillator that oscillates a reference signal for converting the signal reflected from the target into an intermediate frequency; a mixer that mixes the signal reflected from the target with the reference signal; and a mixer that amplifies the intermediate frequency output from the mixer. An intermediate frequency amplifier, a local oscillator for converting this intermediate frequency into a video frequency, a mixer for mixing the output signal of this local oscillator and the above intermediate frequency, and a frequency amplifier for converting the video frequency output from this mixer into a video frequency. A signal processor comprising: a group of video amplifiers that divide and amplify; and a signal processor that outputs only the highest frequency among the frequencies passing through the group of video amplifiers.
