Description

The Tracking Scenario Reader block reads a trackingScenario object or a Tracking Scenario Designer session file and outputs platform poses and simulation time. You can configure the block to optionally output detections, point clouds, emissions, sensor and emitter configurations, and sensor coverages from the scenario.

Examples

Track Point Targets in Dense Clutter Using GM-PHD Tracker in Simulink

Radars generally receive echoes from all surfaces in the signal path. These unwanted back-scattered signals or echoes generated from physical objects are called clutter. In a densely cluttered environment, missed detections and false alarms make tracking objects a challenging task for conventional trackers such as Global Nearest-Neighbor (GNN) tracker. In such an environment a PHD tracker provides better estimation of objects as it can handle multiple detections per object per sensor without clustering them first. This example shows you how to track points targets in dense clutter using a Gaussian mixture probability hypothesis density (GM-PHD) tracker with a constant velocity model in Simulink. The example closely follows the Track Point Targets in Dense Clutter Using GM-PHD Tracker MATLAB® example.

Input

The fields of each platform structure is:

Field	Description

ClassID	Platform classification identifier, specified as a nonnegative integer
Position	Position of the platform, specified as a 3-element real-valued vector. If the IsEarthCentered property of the scenario is set to false, specify the position as a three element Cartesian state [x, y, z] in meters. If the IsEarthCentered property of the scenario is set to true, specify the position as a three element geodetic state: latitude in degrees, longitude in degrees, and altitude in meters.

You must pre-define each platform in the scenario before specifying its pose as input. Use this input when you cannot pre-define the platform properties, such as its position, in the scenario. For example, define the platform position in response to positions of other platforms for collision avoidance during the scenario run. Selecting this option disables all block output ports except the default Platforms and Simulation Time output ports.
