The algorithms for the detection of gravitational waves are usually very complex due to the low signal to noise ratio. In particular the search for signals coming from coalescing binary systems can be very demanding in terms of computing power, as in the case of the well known Standard Matched Filter Technique. To overcame this problem, we tested a Dynamic Matched Filter Technique, still based on Matched Filters, whose main advantage is the requirement of a lower computing power. In this work this technique is described, together with its possible application as a pre-data analysis algorithm. A parallel computing implementation of the algorithms is also described and tested. Finally the results on simulated data are reported.
