Data analysis algorithms for gravitationalwave experiments
Abstract
The analysis of the sensitivity of a gravitationalwave antenna system shows that the role of the algorithms used for the analysis of the experimental data is comparable to that of the experimental apparatus. After a discussion of the processing performed on the input signals by the antenna and the electronic instrumentation, we derive a mathematical model of the system. This model is then used as a basis for the discussion of a number of data analysis algorithms that include also the WienerKolmogoroff optimum filter; the performances of the algorithms are presented in terms of signaltonoise ratio and sensitivity to short bursts of resonant gravitational waves. The theoretical results are in good agreement with the experimental results obtained with a small cryogenic antenna (24 kg).
