The object sensing device comprises a transmitter and a receiver. The transmitter includes an irradiation unit that irradiates an RF transmission signal having a periodically swept frequency. The receiver includes a reception unit that receives an RF reception signal being a reflected wave of the RF transmission signal reflected by the target, an IF signal generation unit that generates an IF signal by mixing the RF transmission signal with the RF reception signal, a position detection unit that detects a position of the target, based on amplitude of a one-dimensional spectrum calculated from the IF signal for each period in which the frequency is swept, and a displacement detection unit that detects displacement of the target, based on a phase of the one-dimensional spectrum at the detected position of the target.
