Abstract (en)
[origin: JP2018072318A] PROBLEM TO BE SOLVED: To provide an ultrasonic moving body detection device that can recognize a reflection wave from a moving body and detect the moving body even if the reflection wave is small or even in an environment in which there is another object.SOLUTION: An ultrasonic moving body detection device 1 includes: a transmission unit 15 for converting a transmission signal modulated with a particular code into an ultrasonic wave and transmitting it; reception units 21 and 25 for receiving a reflection wave generated by an object reflecting the ultrasonic wave, converting it into a reception signal, and demodulating it; a correlation value calculation unit 31 for calculating a correlation value between the demodulated reception signal and the particular code; a difference calculation unit 33 for calculating difference of prescribed two frames when a correlation value corresponding to one cycle of the particular code is set to one frame; and a moving body detection unit 34 for determining that a moving body is detected when the difference is larger than a prescribed threshold value.SELECTED DRAWING: Figure 1
