Radar Update Rates

Recommended Posts

I assume you are going to have a way to incorporate realistic radar coverage. Will there be an way to define the radar site's rate of rotation and a way to define a site's ceiling. For instance an ASR radar updates faster than a LRR radar due to one is designed for long range and the other one is designed for short range so the rate of turn and update is slower for the LRR. For instance setting up an ASR radar only to be designed to view up to 20k feet or so.

This actually doesn't answer the question I asked. All this says is the refresh rate is high. Not to the specifics of the question I posed. In the FAA we primarily use two fundamentally different radars for in air surveillance. The ASR is a terminal based radar. It has fast rotation and therefore a fast update rate. But in the high altitudes we use a LRR. Since it is designed for long range surveillance so the rotation must be slower to receive a radar return at greater distances otherwise the radar wouldn't get the return . This was my first question. This has nothing to due with the connection update rate  for pilots. Also the ASR radars are not used above a certain height above the ground so being able to set a ceiling per radar site would allow this to be an option in a realistic radar mode. If both of these are an option then fundamentally you could in theory develop a radar definition for ASDE-X radar specifically as their rotation speed is even higher than ASR radar sites.
