For multiple radars support and additional features such as KML export, take a look at the Radar Coverage Tool Pro.
Shuttle Radar Topography Mission terrain data is used to calculate the radar visibility. This dataset covers latitudes between 60.395 degrees North and 56.0 degrees South, with a resolution of approximately 90m.
The position and height of the radar are specified, together with the end range, top beam angle and bottom beam angle. Targets that would be above or below the beam are deemed not to be visible.
The units used to display heights and distances may be toggled between "Metric" (metres for height and distance) and "Feet, NM" (feet for height and nautical miles for distance).
Radar and Target Modelling
The SPx Radar Coverage Tool is not a modelling tool. It does not use target cross-section and radar characteristics to predict detection. It uses line-of-sight processing to consider whether a target is potentially visible to the radar based on the beam of the radar, height of the radar and target and presence of terrain.
Multiple target heights may be specified with each height being assigned a colour. The transparency of the first colour used is configurable, with the other colours being gradually more transparent as they represent higher target heights. The areas on the map shown in this colour are where targets at the associated height would be line-of-sight visible to the radar, and within the top and bottom beam angles. Target heights may be specified as above sea level or above local ground level.
The SPx Radar Coverage tool displays coverage information overlaid on an OpenStreetMap view. A snapshot of the current view may be saved to an image file using the "Save Screenshot…" button.
