beam_width {bioRad} | R Documentation |
Calculates the width of a radar beam as a function of range and beam angle.
beam_width(range, beam_angle = 1)
range |
numeric. Range (distance from the radar antenna) in m. |
beam_angle |
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.
#' # beam width in meters at 10 km range: beam_width(10000) # define ranges from 0 to 1000000 meter (100 km), in steps of 100 m: range <- seq(0, 100000, 100) # plot the beam width as a function of range: plot(range, beam_width(range), ylab = "beam width [m]", xlab = "range [m]")
