Abstract:

The required signla-to-noise ratios for short-term detection of a narrowband Gaussian signal process in Gaussian noise are computed for false alarm probabilities 10 sup -n, n 118 detection probabilities 0.5, 0.7, 0. 9, 0.99 and observation-time analysis-bandwidth products in the range of 0 to 100. No assumptions are made about Gaussian statistics of the decision variable, or about long observation intervals. It is found that the required signal-to- noise ratios are significantly greater in some cases than those predicted from a simple deflection criterion of system performance.
