: The system accounts for complex factors like terrain elevation (using DTED data), air temperature, and humidity.

: A more recent study (2020) on Analysis of Target Detection Performance discusses how AREPS is used to model abnormal atmospheric conditions like "ducts" that can trap radar signals and extend their range. What AREPS Actually Does Areps Free

: It evaluates UHF/VHF and HF communications, helping operators understand where signals might be blocked or enhanced by weather. : The system accounts for complex factors like

: It calculates the probability of a radar detecting a target based on height, range, and bearing. Areps Free
