  • Publication number: 20220260698
    Abstract: A radar distance measuring device having a BPF type ??ADC and capable of controlling a band of a BBF and modulation setting of a chirp signal in conjunction therewith is provided. A chirp signal generated by a synthesizer is distributed to a transmission antenna and each of mixers at a reception side. The chirp signal is amplified and irradiated from the transmission antenna to an object as radar. The radar reflected by the objects received by reception antennas, and is then mixed with the chirp signal from the synthesizer by the mixers to generate IF signals. These IF signals are respectively outputted to ADCs via anti-aliasing filters. Each of the ADCs is as oversampling ??ADC. The IF signals are sampled by the ??ADC, and are converted into a digital signal.
