Abstract
DREA sea trials require the planning of vessel and sensor locations and movements before and experiment, and the collection of the realized data as it occurs at sea. This non-acoustical data is vital in understanding the measured acoustical results, and is collected by the NADAS shipboard system. A series of computer programs suites has been developed over the years by a variety of authors in order to analyze this non-acoutical data after the experiments. The demands on the software have increased due to user requests and the improved positional accuracy available at sea. This report covers the version of the software that incorporates these changes. The modifications to the software included a general cleaning up of the code and converting it to run on the Linux operating system. The major enhancements include the use of the World Geodetic System-84 rather than a simple spheroid to represent the earth. The computations of relative ranges, relative and geographic bearings, bistatic aspect, and bistatic angles given source, receiver and target information have been implemented. Additionally, further quality assurance testing of the data has been added and the ability to use the software for trial planning purposes. This report will describe the software suite, the algorithms used, and the typical usage of the programs.
