Kalman filter gating contracts innovation statistics, study finds

By PulseAugur Editorial · [1 sources] ·

A new paper details how validation gating in Kalman filters can lead to a contraction of innovation statistics. The research shows that measurements below a certain threshold, when used for state updates, result in innovation statistics that are conditioned on the gate rather than nominal. This effect, which causes a deterministic contraction of the innovation covariance, is further exacerbated by nearest-neighbor association methods. AI

    Selection-Induced Contraction of Innovation Statistics in Gated Kalman Filters

    arXiv:2512.18508v3 Announce Type: replace-cross Abstract: Validation gating is a fundamental component of classical Kalman-based tracking systems. Only measurements whose normalized innovation squared (NIS) falls below a prescribed threshold are considered for state update. While…
