Inputs

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
lat0, lon0, alt0: ellipsoid geodetic coordinates of observer/reference (degrees, degrees, meters)
spheroid: referenceEllipsoid
angleUnit: string for angular units. Default 'd': degrees

outputs

x,y,z: Earth Centered Earth Fixed (ECEF) coordinates of test point (meters)

function [x,y,z] = aer2ecef(az, el, slantRange, lat0, lon0, alt0, spheroid, angleUnit)

arguments
  az {mustBeReal}
  el {mustBeReal}
  slantRange {mustBeReal, mustBeNonnegative}
  lat0 {mustBeReal}
  lon0 {mustBeReal}
  alt0 {mustBeReal}
  spheroid (1,1) matmap3d.referenceEllipsoid = matmap3d.wgs84Ellipsoid()
  angleUnit (1,1) string = "d"
end

% Origin of the local system in geocentric coordinates.
[x0, y0, z0] = matmap3d.geodetic2ecef(spheroid, lat0, lon0, alt0, angleUnit);
% Convert Local Spherical AER to ENU
[e, n, u] = matmap3d.aer2enu(az, el, slantRange, angleUnit);
% Rotating ENU to ECEF
[dx, dy, dz] = matmap3d.enu2uvw(e, n, u, lat0, lon0, angleUnit);
% Origin + offset from origin equals position in ECEF
x = x0 + dx;
y = y0 + dy;
z = z0 + dz;
