WAVEFORM GENERATION METHOD, RADAR DEVICE, AND OSCILLATOR FOR RADAR DEVICE

摘要

It is possible to generate D/A conversion voltage in which an error generated by numeric irregularities of a D/A conversion element such as a resistor constituting a D/A converter (11) is corrected. A radar device and an oscillator for a radar device has input data obtained by converting input data of a D/A converter (11) in the minimum conversion unit or in the minimum conversion unit multiplied by an integer and D/A conversion data indicating a conversion amount with the voltage D/A-converted. The waveform generation method generates voltage D/A-converted according to a desired waveform by successively giving input data to a D/A converter (11) at the timing when voltage of the desired waveform changing with lapse of time becomes substantially equal to the voltage D/A-converted.
