LOWHIGH NOISE LEVEL TRACK ERROR KALMAN FILTER RESOLVE

Same returns. Better track.

Resolve is measured head to head against the Kalman filter, the standard for sixty years, in post-mission analysis on the same data. It produces the better track.

Both start from the same returns. As the noise rises, the Kalman filter's track error climbs with it. Resolve's stays low, because it weighs every return it has seen and every one that follows against the physics of flight and the geometry of the radar, and reports where the target is with an exact probability attached. A sensor upgrade delivered in software.

Tested with Riverside Research. The curves are illustrative. Post-mission analysis today. Real time is on the roadmap.

What it does

Two stages on every return. Search, then infer.

Resolve starts from one probabilistic model of the target's motion and the radar's geometry. Search decides which return belongs to which object. Infer reasons over the whole track and returns an exact probability for every position.

  1. 01

    Search

    Across time

    Decides which return belongs to which object across time, so a sharp turn does not start a new track.

  2. 02

    Infer

    Σ P = 1.000

    Reasons over the whole track, backward and forward, and returns an exact probability for every position.

A target turns as the returns thin out in a simulated run. The track holds.
Where it stands

Post-mission tracking today. Real time on the roadmap.

Feed it a recorded run. It computes the track, with an exact probability on every position. Real time is on the roadmap.
