Calculates the width of a radar beam as a function of range and beam angle.
beam_width(range, beam_angle = 1)
Numeric. Range, i.e. distance from the radar antenna, in m.
Numeric. Beam opening angle in degrees, typically the angle between the half-power (-3 dB) points of the main lobe.
numeric. Beam width in m, typically the full width at half maximum (FWHM).
