A Review of the Statistical Theory of Signal Detectiond include the classical theory of hypothesis testing, detection of known signals in white noise, maximum likelihood estimation of unknown parameters, the application of nonlinear filtering in signal detection and the use of pre-whitening filters to handle correlated noise.

Sample Covariance Techniques in the Detection of Gravitational Wavesion of the Green’s or Impulse response function from the time delayed movement estimates using the Winer-Volterra expansion is discussed for linear and non linear systems. The effect of additive outliers on the power spectral density estimates is illustrated and recent reviews referred. Finally the

Parametric Transducers and Quantum Nondemolition in Bar Detectorsre a quantum nondemolition observable and thus potentially exceed the “quantum limit” for bar detectors. A more immediate benefit of this type of transducer to the development of gravitational wave antennae is the reduction of the requirements on the electrical Q and the pump phase noise. We summari

Round Table Discussion — Gravitational Wave Detectorsss detectors using laser interferometry and the first concrete sign of a long baseline detector being funded has appeared in response to a proposal by the Orsay and Pisa groups to INFN in Italy. Bar detectors have continued to develop, with the possibility of having several bars operating in coincid

Spacecraft Gravitational Wave Experimentschnology involved is sophisticated, the “raw” sensitivity of current generation experiments has been insufficient to produce a detection. To extract the maximum information from the Doppler data requires careful consideration of noise statistics, of how the noises map into the Doppler frequency obse

Gravitational Wave Experiments with Resonant Antennase metric tensor perturbation h(t) at the antenna resonance. By means of proper optimum filters, like the Wiener filter, it is possible to reach a sensitivity which is basically limited by the noise of the electronic amplifier. For one cryogenic antenna with mass M=2300 kg and temperature T=20 mK the

Gravitational Antenna Bandwidths and Cross Sectionstes. For monochromatic continuous signals, the new approach gives the same cross sections as derived in 1960..A new method for data recording and analysis is proposed. This gives bandwidths several orders larger than are available by recording the output of an optimal filter..Means are suggested for

Comparison of Bars and Interferometers: Detection of Transient Gravitational Radiationor the detection of gravitational-wave bursts (e.g., supernovas, particle- black hole interactions), the bar antenna shows its resonant nature with a sensitivity that is broadly peaked near the bar frequency, while the interferometer shows a smooth f. frequency response (for a fixed gravitational en
