The other platforms have radars with smaller scan regions, allowing them to revisit the targets at a higher rate.Necessary cookies are absolutely essential for the website to function properly. The small number of detections from this platform is due to its radar's 360 mechanical scan, which limits how frequently its beam can revisit a target in the scenario. The blue airborne radar with the rotating array generates the fewest number of detections (only 4 detections for these two targets), but these detections are the most precise (smallest ellipses). In this case, the platform's radar reports detections at 0 degrees with an uncertainty in elevation corresponding to the elevation field of view. This is because the linear arrays on this platform are unable to provide estimates in elevation. The ellipsoids have small axes in the range and azimuth directions but have very large axes along the elevation direction. Notice the large uncertainty in elevation of the red detections generating from the airborne platform (Platform 2) that uses two linear arrays. Set the UpdateRate to 0 to let trackingScenario determine the next update time. The trackingScenario can advance at a fixed time interval or automatically determine the next update time. For each step forward in the scenario, detections are generated from each platform. The following loop advances the platform and target positions until the end of the scenario.
