beam_range

Calculates the range (i.e. slant range) given a distance measured along the earth's surface
(i.e. down range) and beam elevation.

Extract, visualize and summarize aerial movements of birds and
insects from weather radar data. See <doi:10.1111/ecog.04028>
for a software paper describing package and methodologies.
