Design and Simulate Tracking Scenario with Tracking Scenario Designer

Use trackingScenarioDesigner with an existing session file. Using the application, you can add, modify, or remove platforms, monostatic radar sensors, and trajectories of all objects in the scenario. You can also export the scenario as a MATLAB script for further analysis.

How to Simulate Out-of-Sequence Measurements

Simulate out-of-sequence measurements (OOSMs). OOSMs occur in multisensor systems when detections from some sensors arrive at the tracker after the tracker has processed detections of the same or earlier time from other sensors. Several reasons, mostly sensor processing lag and sensor-to-tracker connection delays, can cause this problem. For more about OOSMs, see Introduction to Out-of-Sequence Measurement Handling
