For a presentation to an AS-Level class, can anyone give me some decent information/calculations about radars. Any good sites for info will also be appreciated.

Radars work by sending out radio waves and then receiving the reflected waves that bounce off of objects in their path. The time it takes for the waves to return helps determine the distance and direction of the objects.
Primary radar uses radio waves to detect and track any object in its range, while secondary radar relies on an object's transponder (a device that responds to radar signals) to identify and track it.
The range of a radar is determined by the power of the transmitter, the sensitivity of the receiver, and the height of the radar antenna. The curvature of the Earth also plays a role in the radar's maximum range.
Radar cross section (RCS) refers to the amount of energy that is reflected back to a radar by an object. It is an important consideration in radar technology because it affects the ability to detect and track an object, as well as the accuracy of the radar's measurements.
Weather radars use radio waves to detect and track precipitation in the atmosphere. This data is then used to create visual representations of weather patterns, which can help meteorologists make more accurate predictions about future weather conditions.
