ENU2AER convert ENU to azimuth, elevation, slant range
Contents
Inputs
- e,n,u: East, North, Up coordinates of test points (meters)
- angleUnit: string for angular units. Default 'd': degrees
outputs
- 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
function [az, elev, slantRange] = enu2aer(east, north, up, angleUnit)
if nargin < 4
angleUnit = 'd';
end
if abs(east) < 1e-3, east = 0.; end
if abs(north) < 1e-3, north = 0.; end
if abs(up) < 1e-3, up = 0.; end
r = hypot(east, north);
slantRange = hypot(r,up);
elev = atan2(up,r);
az = mod(atan2(east, north), 2*pi);
if strncmp(angleUnit, 'd', 1)
elev = rad2deg(elev);
az = rad2deg(az);
end
