PURPOSE ^

aer2enu convert azimuth, elevation, range to ENU coordinates

SYNOPSIS ^

function [e, n, u] = aer2enu (az, el, slantRange, angleUnit)

DESCRIPTION ^

aer2enu  convert azimuth, elevation, range to ENU coordinates

 az, el, slantrange: look angles and distance to point under test (degrees, degrees, meters)
 az: azimuth clockwise from local north
 el: elevation angle above local horizon
 angleUnit: string for angular units. Default 'd': degrees

 Outputs
 -------
 e,n,u:  East, North, Up coordinates of test points (meters)
