Patent ID: 7233279

Claim:
A pulse radar, comprising: a pulse signal generation unit for generating pulse signals with at least two different cycles; a pulse signal switching unit for switching the pulse signals generated in the pulse signal generation unit in a predetermined interval and outputting the signals; a pulse signal sending unit for sending the pulse signals from the pulse signal switching unit toward objects; a reflected signal receiving unit for receiving reflected signals from the objects, and storing receiving data that contains at least data of receiving intensity of the reflected signals and a receiving time of the reflected signals in its storage unit; a reflected signal data acquisition unit for obtaining reflected signal data of every reflected signal for all the pulse signals with different cycle from the receiving data stored by the reflected signal receiving unit; and a reflected signal identification unit for evaluating the receiving intensity of the reflected signals received during a predetermined time period after transmission of a reference pulse signal on each of the reflected signal data of the pulse signals with different cycles obtained by the reflected signal data acquisition unit to determine a lowest value of the receiving intensity, and identifying the reflected signal as a reflected signal of the reference pulse signal only when the lowest value is at least as large as a predetermined receiving intensity.
