Abstract (in Japanese) (See Japanese page) 
(in English) This paper presents an analysis of the binary coded frequency shift keyed signals for the ultrasonic ranging system, consisting of piezoelectric transducers and a digital polarity correlator. A numerical evaluation of the output signal shows that the signal to noise ratio degrades only a small amount comparable with that obtained by direct digital correlators. The bandwidth of the transducers has to be included into the calculation, so that the width of the main peak increases with decreasing the bandwidth of the transducers. The analysis should provide us useful insight into how the system should be realized and performed.
