GPAS - Generic Post Analysis System

Array's Generic Post Analysis System (GPAS) is a flexible processing system that processes both acoustic and non-acoustic data. At the core of the system is the Scalable Generic Signal Processor (GSP), which acts as a signal processing slave for multiple Operator Workstations (OWs).

U212A Submarine The UAAS is the German implementation of Array's GPAS technology.

The GSP is built upon the open source of the Message Passing Interface (MPI), the Vector Signal Image Processing Library (VSIPL) and Linux. These design choices make the GSP portable, scalable and economical.

The OWs are Windows PC workstations that provide Input/Output (I/O) and GSP control through GUIs. Each OW can have its own independent processing tasks and displays.

Using Microsoft Windows, the MFC library and C++ for the OWs make upgrading to the latest PC and graphics technology very cost effective.

A key characteristic of the GPAS is its ability to easily accept data from various sensors and geometries. The GPAS provides a Universal Sonar Beamformer which can process data from uniform linear and circular arrays and also allows the user to enter an arbitrary 3D array geometry. This allows the user to beamform data from active and passive sonobuoy, TAS, and hull-mounted sonar sensors. The user can also beamform data from fixed bottom horizontal and vertical sensor arrays.

As a generic processing tool, the GSP is capable of efficient processing for the following applications:
