I need to convert a polar plot into a short array of 3-5 values. This array should describe the polar plot as best as possible.
For example, I know that I can use the beamwidth which is also known as the half power. This is the angle between the left and right -3 dB point:
I also know that I can use the the ratio between the surface of the polar plot versus the whole 360° plane.
Thus, so long I only have two values in the array:
- Ratio polar plot vs plane
But are there other values that can describe the polar plot ? And also, how can I have a value which describes second biggest lobe ?
