Title:
REFLECTION POINT ESTIMATION DEVICE AND REFLECTION POINT ESTIMATION METHOD
Document Type and Number:
WIPO Patent Application WO/2020/208684
Kind Code:
A1
Abstract:
A reflection point estimation device (100, 100a) comprises: an inside dimension acquiring unit (101) for acquiring inside dimension information indicating the inside dimension of an anechoic chamber (10); a transmission position acquiring unit (102) for acquiring transmission position information indicating the position of a transmission antenna (20) for emitting a transmission signal; a reception position acquiring unit (103) for acquiring reception position information indicating the position of a reception antenna (30) for receiving the transmission signal emitted by the transmission antenna (20); a signal specifying unit (111) for specifying a first transmission signal which is a direct wave and a second transmission signal which is a reflected wave, from among transmission signals received by the reception antenna (30); a signal interval output unit (120) for outputting signal interval information indicating a time interval between the first transmission signal and the second transmission signal; and a reflection point estimation unit (130, 130a) for estimating the position of a reflection point on an inside wall of the anechoic chamber (10), at which the second transmission signal is reflected, on the basis of the inside dimension information, the transmission position information, the reception position information, and the signal interval information.
