Abstract
In a direction detecting device, a transmitting wave generator encodes a transmitting signal with a code having a high autocorrelation so as to generate a transmitting wave. A transmitter transmits the transmitting wave and a plurality of receiver elements receives a reflected wave reflected by an object. A direction calculating unit calculates a direction of the object based on a phase difference between a correlation value calculated based on the reflected wave received by one of the receiver elements and a correlation value calculated based on the reflected wave received by another one of the receiver elements, a distance between the one of the receiver elements and the another one of the receiver elements, and a wavelength of the transmitting wave.
