Introducing The Edge of Decision

Tomorrow’s military advantage will come not simply from generating more data, but from extracting more intelligence from the data already available.

Voyant is launching The Edge of Decision, a new series exploring the technologies that determine what defence operators can see, understand and act upon. The first issue, Making sense of uncertainty looks at one of the most important, but often least understood, components within a sensing system: the tracking filter.

Tracking filters sit between raw sensor data and the operational picture presented to the user. They influence how uncertainty is interpreted, which information is retained and how confidently a target can be detected and followed. The choice of filter can therefore have a direct impact on operational effectiveness.

Why does the filter matter?
It determines how uncertainty is interpreted, which information is retained and, ultimately, what the operator sees.

For decades, Kalman filters have provided the foundation for target tracking. They remain highly effective in many situations, but complex and uncertain environments are increasing the need for approaches capable of retaining and interrogating multiple possibilities as conditions evolve.

Particle filters offer that capability. However their operational use has historically been limited by the computing power required to run them – particularly on platforms where size, weight and power are constrained.
