geodetic2aer

PURPOSE ^

geodetic2aer from an observer's perspective, convert target coordinates to azimuth, elevation, slant range.

SYNOPSIS ^

function [az, el, slantRange] = geodetic2aer(lat, lon, alt, lat0, lon0, alt0, spheroid, angleUnit)

DESCRIPTION ^

geodetic2aer   from an observer's perspective, convert target coordinates to azimuth, elevation, slant range.

 Inputs
 ------
 lat,lon, alt:  ellipsoid geodetic coordinates of point under test (degrees, degrees, meters)
 lat0, lon0, alt0: ellipsoid geodetic coordinates of observer/reference (degrees, degrees, meters)
 spheroid: referenceEllipsoid parameter struct
 angleUnit: string for angular units. Default 'd': degrees, otherwise Radians

 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

CROSS-REFERENCE INFORMATION ^

This function calls: This function is called by:
