Simulation of Passive and Multistatic Active Sonar Contacts
Fields of distributed passive and multistatic active sonar sensors provide a surveillance capability against quiet submarine threats in ASW scenarios. A significant challenge of heterogeneous, multi-sensor systems is the successful fusion of information from the various sensors to enable robust target detection, classification, localization, and tracking. Sensor fusion and tracking algorithms m...
متن کاملAn ASW (Anti-Submarine Warfare) Simulator on Smart Phones
As modern weapon systems become complex and expensive, there is an increasing need to predict the effectiveness of a new weapon system before the actual development. In this paper, we present an ASW (Anti Submarine Warfare) simulator to measure the effectiveness of a TAS (Towed Array Sonar) on smart phones. Our simulator is composed of Red and Blue submarine model, Environment model (i.e. sea) ...
متن کاملDynamically coupled 3D visualization and real-time simulation as an aid to developing mental models of sonar
Training sonar operators for Anti-Submarine Warfare (ASW) in complex environments is challenging. Performance deficiencies are the product of errors in both analysis and employment. Experts use mental models to interpret displays and reason about the underlying scenario in order to perform analysis under uncertain conditions and achieve more optimal tactical-system employment. To accelerate the...
متن کاملPassive Sonar Performance Modeling
Accurate passive acoustic (ASW) performance modeling requires high-fidelity environmental inputs, accurate acoustic propagation and noise modeling as well as the integration of the statistics of the detection of quiet signals in a dynamic environment. In this paper we present the combination of Parabolic Equation modeling with state of the art statistical signal processing to be able to incorpo...
متن کاملModelling broadband scattering from shelled spheres in a waveguide
The broadband scattering characteristics of a target may be used to distinguish echos from a target of interest from those of clutter. This type of classification is of interest in many sonar applications: ASW, torpedo, surface mines, and diver detection. In a shallow water situation the original sonar pulse and the echo from the target will consist of a sequence of pulses corresponding to the ...
