|TARGT - Water-based Acoustic Scoring|
Trident Research embarked upon the development of the TARGTTM system based upon a recognized need for weapons testing and training in broad ocean areas. As noted in the August 2006 issue of the InsideGNSS magazine:
Several methods have been used to determine the location of an offshore impact event. All these methods rely on knowing the location of the observation point and the direction or distance to the observed event. GPS provides the primary method for determining the location of the observation sensors. Direction can be measured by sighted instruments such as optics or radar, while distances can be measured by active radar and passive underwater acoustic arrival time. The Tactical Acoustic Realtime Geolocation and Training (TARGTTM) system, developed by Trident Research LLC, is a distributed array of underwater acoustic sensosrs and shipboard command and control station which incorporates GPS, acoustical processing, and communiciations to provide a low cost underwater acoustic method for locating offshore weapon impacts.
Trident has exploited some of the inherent advantages of underwater acoustics to provide a remote over water weapons scoring and training capability with its TARGTTM system. Among these advantages include the ability to operate during the day or at night, in poor environmental conditions including fog and heavy precipitation, and in broad ocean areas regardless of sea state or depth of water. Through the deployment of multiple acoustic sensors in and about the impact area, the TARGTTM system is capable of sub-meter accurate 2D weapons scoring in broad ocean areas. Some of the specific capabilities available include:
