ダ装置。 The high-frequency pulse power generated by the magnetron is radiated to the outside from the antenna as a transmission radio wave, and the reflected power from the target is input from the antenna as a reception signal, which is mixed with the high-frequency signal of the local oscillator circuit and converted to an intermediate frequency. In a radar device that takes out video, a readout circuit generates a voltage proportional to the frequency of high-frequency pulse power generated by a magnetron, a voltage-frequency conversion circuit that converts the voltage into a high-frequency signal, and a high-frequency signal between the high-frequency signal and the local oscillator circuit. A byte mixer circuit that mixes signals, a frequency-voltage converter circuit that converts the frequency difference between the output of this byte mixer circuit and an intermediate frequency into a voltage, and a pulse that pulse-modulates the high-frequency signal from the voltage-frequency converter circuit to generate a pseudo received signal. A radar device comprising: a modulation section.
