Device and method for detecting difference in signals generated from multiple channels in single frequency receiver

Abstract

A device for detecting a difference between signals in multiple channels, according to the present invention, may comprise: a plurality of sensors which are arranged geometrically on the same plane, and which detect a plurality of signals transmitted through a plurality of channels respectively corresponding to a plurality of sources, so as to output raw time series measurements for each channel, the plurality of sensors simultaneously measuring signals transmitted through any one of the plurality of channels; a signal processing unit, which process the raw time series measurements for each channel that is output from each of the plurality of sensors, so as to generate processed time series measurements; an data processing unit which calculates a crossing rate for each channel by using the processed time series measurements corresponding to two sensors selected from the plurality of sensors, and which connects the crossing rate between the plurality of sensors; and a change detection unit for detecting a channel in which a signal difference occurs in the crossing rate for each channel.
