Claim One:
1. A heart rate estimating apparatus comprising: a transmitter configured to transmit microwave with respect to a subject; a receiver configured to receive and detect reflected wave from the subject irradiated with the microwave, and acquire a detected result; a sensor configured to sense a movement of the subject, and acquire a sensed result; a storage unit configured to store a program; and a processor configured to execute the program stored in the storage unit and perform a process including performing a first frequency analysis of the detected result to obtain a first result of the first frequency analysis versus frequency, wherein the first result includes feature points that are formed by peaks having a first amplitude or greater; performing a second frequency analysis of the sensed result to obtain a second result of the second frequency analysis versus frequency, wherein the second result includes feature points that are formed by peaks having a second amplitude or greater; and estimating a heart rate based on feature points remaining after excluding the feature points included in the first result and located at frequencies within a predetermined frequency range of frequencies of the peaks forming the feature points included in the second result.
