Dynamic matched filters for gravitational wave detection

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 overcome this problem, we tested a dynamic matched filter technique, 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. The results on simulated data are also reported.
