. PpUmal and Conventional Space - Time processing in Fiow Noise

A systematic approach is developed as a means of characterizing optimal and conventional space-time detection of a Gaussian signal in colored Gaussian flow noise with line arrays. Discrete arrays of sensors, as well as continuous finite observation intervals, are considered. Using the likelihood ratio as a starting point, exact solutions are formulated, specifying the optimal instrumentation for a rational noise model. These solutions provide the theoretical framework to determine upperbound detection performance and permit examination of the role played by the noise spectra in influencing the optimal instrumentation and its performance.
