Weboutput. The matched filter got its name because it uses a known signal pattern to detect the presence of the same pattern in the received signal. Because the matched filter is the optimal linear filter for maximizing the signal-to-noise ratio in the presence of additive noise, it has been widely used in radar, sonar, and communication applications.
