Probability of Detecting Ships with an OTH Radar System
Abstract
An over-the-horizon (OTH) radar uses ionospheric reflection of high- frequency radio waves to propagate to areas far beyond the normal radar horizon. Two principle probabilities are associated with an OTH radar; the probability of successfully propagating to a given region via the ionosphere and probability of detecting a target in sea clutter, given that propagation occurred. A particular radar system was examined and tables of probabilities were generated for various ionospheric and target parameters. An example illustrates the method of combining these probabilities to obtain a composite probability of detection. The probability of propagating was calculated by a computer program that used radar parameters, the ionospheric parameters, the geographical location, and the time of day and year as inputs. The probability of detection involved a computer implementation of the radar range equation.
