To use values in radians, specify the angleUnit argument as 'radians'. 0 that builds a vector from its azimuthal coordinates (eyes glazing over zero or 180 degrees (= π radians), the azimuth is arbitrary. Azimuths are measured clockwise from north. Even with these restrictions, if the polar angle (inclination) is 0° or 180°—elevation is −90° or +90°—then the azimuth angle is arbitrary; and if r is zero, both azimuth and polar angles are arbitrary. It is also evident from the following figures that for the default orientation of elevation = 90 deg and azimuth = 0 deg, the sensor or antenna frame coincides with the subcomponent reference frame: The azimuth angle of a vector is the angle between the x-axis and the orthogonal projection of the vector onto the xy plane. In geographic coordinates the azimuth is the longitude $\lambda$ and the elevation is the latitude $\phi$, while in celestial coordinates the azimuth is the right ascension $\alpha$ and the elevation is the declination $\delta$. 7071]. Azimuth angles lie between –180 and 180 degrees. I just calculate the vector's azimuth using the B vector components in x-y plane. The azimuth angle can range from -180 degrees to 180 degrees. To define the coordinates as unique, the user can assert the convention that (in these cases) the arbitrary coordinates are set to zero. Coordinates are azimuth, elevation and range. 3 (10−12 degrees) φλ=−110 λ =−40 λ = 30 λ = 100 λ = 170 The notation for spherical coordinates is not standard. Az = tan-1 (-r E / r S). A more complete explanation of the coordinate systems can be found : in [1] and [2].
