A Mobile Decision Aid for Determining Detection Probabilities for Acoustic Targets
Abstract
The Army Research Laboratory (ARL) has developed a physics based Acoustic Battlefield Aid (ABFA) for acoustic sources and sensors. This application computes numerous output parameters (e.g., probability of detection, transmission loss, signal-to-noise ratio, etc) for a number of acoustic sources and sensors (if required). Probability of detection (POD) output would seem to be particularly of interest to lower echelon units, e.g., in determining how close enemy tanks could approach before being heard (by either the human ear or some other acoustic sensor). As a result, a prototype application has been developed that allows the POD for a user specified target/sensor pairing given the direction and distance between the two. Commercial wireless communications are used to link the mobile device (a Compaq 3650 personal digital assistant) to a remote laptop server. The server consists of a set of dynamic linked libraries written in C that contain several functions that access an acoustic propagation table. This table is a function of the environmental conditions, and for the prototype, is simply a static table. Eventual dynamic creation of the table from an existing gridded prognostic meteorological database (residing on the Army's tactical command and control system for weather) is anticipated. Tactical wireless comms would also replace the short-range commercial comms.
