The Angle of Arrival (AoA) is a critical measurement in various fields, including communications, navigation, and physics. This concept helps determine the angle at which a signal or object arrives at a given point, which is essential for accurate positioning or analysis. By understanding this angle, professionals in these fields can make better-informed decisions and enhance their operations.
Formula
The formula to calculate the Angle of Arrival (θ) is:
θ = atan(h/d)
Where:
- h is the height
- d is the distance
The result will be in degrees.
How to Use
To use the Angle of Arrival calculator:
- Enter the height (h) in the first input field.
- Enter the distance (d) in the second input field.
- Click on the “Calculate” button to get the angle of arrival (θ) in degrees.
Example
If you have a height of 50 meters and a distance of 100 meters, input these values into the calculator and click “Calculate”. The Angle of Arrival (θ) will be calculated as:
θ = atan(50/100) = 26.565°.
So, the Angle of Arrival (θ) is approximately 26.57 degrees.
