Title:
DISTANCE MEASURING DEVICE, DISTANCE MEASURING METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2022/097749
Kind Code:
A1
Abstract:
This distance measuring device is provided with a signal processing unit which transmits a frequency modulated pulse wave toward a target, and which employs Prony's method, using an exponential function having an argument with a real part and an imaginary part, to fit a signal obtained by inverse correlation, in the frequency domain, of an echo wave that has been reflected by the target and has returned with the transmitted pulse wave.
