SORAPS (SOnar RAnge Prediction Software) is a software program for calculating acoustic loss fields and the performance of systems based on underwater acoustic wave propagation, such as SONAR and digital communication systems. This software is powerful because it operates in true 3D by interfacing with GHOM (Geographic, Hydrographic, Oceanographic, and Meteorological) 3D databases and refines the calculation of the characteristics of acoustic channels established between a reference point in the water column and a surrounding point cloud.

SORAPS operates in "Web Service" mode and therefore does not require powerful processors on the client's PC, which simply connects to the SEAGNAL server URL. In addition to truly 3D calculations of loss-of-interest fields, SORAPS can predict the performance of a SONAR, whether active or passive, mono- or bi-static, and addresses detection (capability to detect a target) and vulnerability (capability to be detected) issues by leveraging the Sonar Equation in various ways.

SORAPS also predicts the performance of a digital acoustic communication system in terms of its ability to deliver a message sent to a point cloud in the surrounding 3D volume, or to receive a message sent by the points in this cloud.
