Number of Targets Threatened Simultaneously (NOTTS) in Conjunction with over the Horizon Back-Scatter (OTHB) Radar Coverage

Abstract

Number of Targets Threatened Simultaneously (NOTTS) is a measure of the presence (in a background of unknowns) of a surprise attack on the U.S. retaliatory force. Four NOTTS indicators PEAK, KURTOSIS, RIDGE, and P1, P2, and P3 are defined and evaluated using the J5YA Raid Recognition Algorithm for a bomber or cruise missile raid against SAC and C3 target sets. Scatter charts showing background noise produced by commercial traffic, raid plus noise combined are presented and used to describe the setting of reaction thresholds. The effect of time of day, probability of radar detection, and the choice of target set and raid design on reaction threshold are discussed. Although ideal settings of indicators are practical in the cases discussed, attention is drawn to the limited data available for modeling of unknowns in OTHB coverage. Keywords include: Raid recognition; Targets threatened simultaneously, bomber or cruise missile raid, background traffic, and setting reaction thresholds.
