Abstract
A wireless communication apparatus includes an analog receiving unit, a phase calculator, a time variation calculator, and a chirp radar determination unit. The analog receiving unit obtains a receiving signal from a radio wave. The phase calculator calculates a phase of the receiving signal. The time variation calculator calculates a frequency of the receiving signal based on the phase. Moreover, the time variation calculator further calculates a time variation of the frequency. The chirp radar determination unit determines whether the receiving signal is a chirp radar or not based on the time variation.
