A Geodesic Flow Particle Filter For Nonthresholded Radar Tracking

Homotopy methods are an emerging approach to particle filtering that avoid numerical deficiencies of standard particle methods using a particle flow. This correspondence develops a new filter with nonthresholded measurements (i.e., a track-before-detect log-homotopy particle filter). We show the per...

Zusammenfassung:	Homotopy methods are an emerging approach to particle filtering that avoid numerical deficiencies of standard particle methods using a particle flow. This correspondence develops a new filter with nonthresholded measurements (i.e., a track-before-detect log-homotopy particle filter). We show the performance by simulating a rotating pulsed radar forming nonthresholded Range/Doppler maps.
