Abstract

The problem of determining the optimal detector sensitivity number and location of alarm detectors against instantaneous sources was examined in terms of the conventional Gaussian dispersion model for flat terrain. Analytical expressions for the effective detecting area per detector as a function of detector sensitivity were derived for a simple case. Numerical results were provided for general cases. The optimal number and location of alarm detectors were then interred from the effective detecting area per detector.
