This paper presents the development of a matched filter system for muon detection using the muon output trigger signal, provided by the hadronic calorimeter of ATLAS detector, the Tile Calorimeter. A signal processing is done for this muon output to improve its signal-to-noise ratio and detection capability. The performance achieved for this system, using data from the testbeam period, was 96 % of detection efficiency against a false alarm of 10 %. This performance encourages the use of the
