Sonar Range Prediction Models REPAS and REACT (Sonar Afsand Voorspelmodellen REPAS en REACT)
Abstract
The range prediction models REPAS and REACT for passive and active sonars respectively, have been developed at FEL-TNO between 1986 and 1990. These models and the propagation loss model almost on which REPAS and REACT are based, are documented in this report. The report describes also the way in which the reverberation is calculated, which is an important part of the REACT-model. A description is given of two modules, which calculate reverberation and target echo level as a function of time respectively. Afterwards time is converted to detection range for operational use. Finally a method has also been included, for the determination of the threshold level for various detection situations, used in REPAS as well as REACT. With this method also the detection probability can be calculated versus detection range. Some examples of detection range prediction calculated by REPAS and REACT are presented.
