Abstract
To provide an information processing device, an information processing method, and a radar device which are capable of achieving accurate detection of an interference signal.SOLUTION: An information processing device according to an embodiment of the present technology includes a calculation unit and a detection unit. The calculation unit calculates the phase of a beat signal generated based on a transmitted chirp signal, which is transmitted by a transmitting antenna toward an object, and a reflected chirp signal, which is the transmitted chirp signal reflected by the object and received by a receiving antenna. The detection unit detects the presence or absence of an unwanted signal based on the phase of the beat signal, thereby enabling accurate detection of an interference signal.SELECTED DRAWING: Figure 1
