Sensor Data Fusion

Technology Service Corporation (TSC) proposes to apply the Dynamic Logic (DL) algorithm to perform target detection and tracking using data from multiple radar and IR sensor assets in the ballistic missile defense system (BMDS). This iterative algorithm performs these two tasks simultaneously, and can reduce the number of computations required. This can allow the BMDS to allocate additional resources to other critical tasks such as discrimination. TSC has demonstrated that the DL algorithm can detect and track dismounts using measured radar data. Under this Phase I effort, TSC will extend DL processing to perform detection and tracking of ballistic missiles using BMD radars and IR sensors. TSC will also develop a method of fusing raw radar and IR sensor measurements into a common reference frame and develop 3-D track estimates. The enhanced tracking capability and simultaneous target detection can support early engagement strategies such as launch-on-remote and engage-on-remote. In the Phase I Option, TSC will extend the fused DL algorithm to estimate sensor biases. In Phase II, TSC will mature the algorithm and test it on measured radar and IR data, as available, and address more challenging raid scenarios.
