![]() ![]() To do this, enable elevation for the radar and set the elevation mechanical scan limits to search from the ground up to the full elevation field of view. Tilt the boresight of the radar antenna so that none of the elevation span of the beam lies below the ground. Conversely, for an airborne platform, you may desire to point the radar's beam downwards, to survey targets at altitudes below the radar's platform. If you are modeling a ground-based radar, you may want to tilt the radar's boresight upwards so that only the area above the ground is surveyed by the radar. In the preceding section, the boresight of the radar's antenna (black, dotted line) was constrained to lie in the horizontal plane, resulting in half of the radar's beam directed below the horizontal plane. The history of beam and boresight positions are shown in gray scale, with the more recent positions shown as black and the older positions fading to white.ģ60 Degree Azimuth Scan with Tilted Elevation Coverage The radar's current beam is shown as a blue, dashed line. ![]() The radar's boresight is shown as a black, dotted line. The inbound target is detected by the radar when its beam sweeps across its position. The preceding figures show the detection of the inbound target in 3-D and 2-D views. You can learn more about using trackingScenario and theaterPlot from the Introduction to Tracking Scenario and Simulating Sensor Detections example. This function also sets up a theaterPlot to display the locations of the targets, the beam and boresight position for the radar, and the detections generated by the radar. Use the function helperScanRadarModesExample to create a trackingScenario with a platform to mount the radar and three targets. A common example of a 360 degree azimuth scan radar is the airport surveillance radar. These radars provide accurate range and azimuth measurements, but typically do not report elevation for the detected targets. In this mode, radars typically employ a fan beam, which has a narrow field of view in azimuth, but covers a wide elevation span. This mode provides 360 degree surveillance by mechanically scanning the radar's antenna in azimuth. 360 degree azimuth scan is a mode commonly found on both ground and airborne radars. ![]()
