Sony patents method to fix distance errors in radio wave measurements

Patent drawing from the official filing.

Sony has filed a patent for a device that improves distance measurement using radio waves. It corrects the calculated distance by analyzing the angle at which the signal arrives at the antenna.

Why it mattersThis could help make location tracking and communication signals more accurate by accounting for how signals bend or arrive at different angles.

In the filing’s own words

An information processing device includes a correction processing unit configured to perform correction related to distance measurement information calculated on the basis of a propagation time of a radio wave from a transmission device to an antenna, on the basis of information regarding an arrival angle of a radio wave transmitted from the transmission device and received by the antenna.

What exactly they claim (claim 1)

1. An information processing device comprising: a correction processing unit configured to perform correction related to distance measurement information calculated on a basis of a propagation time of a radio wave from a transmission device to an antenna, on a basis of information regarding an arrival angle of a radio wave transmitted from the transmission device and received by the antenna.
