Adaptive Fusion Tracker

Multi-Sensor Composite Tracking Software

Overview

Our Adaptive Fusion Tracker (AFT) system is a real-time multi-sensor correlation system, designed to perform data fusion and composite tracking across air, ground and maritime domains.

The AFT is equally adept at supporting single-sensor target tracking as well as multi-sensor correlation and track. Each track is uniquely identified even though multiple sensors may be providing radar measurement updates to that track. Track data integrity is maintained as objects maneuver and pass between the contributing sensors’ surveillance volumes. AFT’s multi-sensor composite tracking capability provides greater track accuracy and track continuity in situations where no single sensor could have maintained a coherent track picture. These fused tracks provide the operator a single integrated picture (SIP) over the entire multisensor network. The SIP can be viewed locally via the AFT’s web browser interface or remotely via the customer’s command and control (C2) visualization tools.

AFT’s open architecture design is developed using a model-driven development (MDD) approach, generating the software from model. The design allows for significant software reuse and enables Leidos to rapidly develop sensor interfaces and solutions for changing air, ground, and maritime surveillance needs.


Features

The AFT multi-sensor correlator software can be installed on a variety of computing platforms. In addition to the multi-sensor correlator, a comprehensive set of features are available to display, record, validate, and optimize track performance. The AFT’s web browser user interface (UI) allows the user to visualize the single integrated track picture and configure controls. The AFT also includes playback capabilities which allow the playback of recorded sensor data into the AFT and/or the display of the AFT’s recorded track data via a Google Earth API.

Architecture


AFT Software Architecture encapsulating tracker framework and external extensions.

 

The AFT architecture is comprised of core and adaptive components that collectively achieve a reusable and flexible software design to fuse sensor data in a given host platform environment. AFT has been deployed in various situational awareness domains from maritime to air applications.

  • Client adaptation — Provides access to external clients such as C2 systems for situational awareness, data analysis and video cueing.
  • Sensor adaption — Provides standardized interface between air, ground and maritime sensors and the tracker.
  • Track executive — Performs track-to-track correlation and filtering, smooths composite track state and removes sensor bias to improve positional accuracy.
  • System database — Provides common mechanisms, track filters, databases, and communication pathways within the AFT architecture.
  • Platform adaptation — Supports multiple computing environments, operating systems, transport layers and host platforms via COTS communication framework.
