It can, however, still measure radar backscatter at a fixed azimuth angle.

Both the tilt angle from the vertical and the azimuth angle of each antenna are fixed when the system is set up.

Owing to a circular symmetry the electric field will have only a radical component, independent of the azimuth angle.

The horizontal axis is the azimuth angle in degrees (180 is facing south).

Figure 5 shows a schematic diagram of an electron beam incident on the sample at different azimuth angles.

Rotating the sample changes the intensity of the diffracted beams due to their dependence on the azimuth angle.

The contribution for a particular ray with azimuth angle and passing a transparent part of the object plane from to is:

The azimuth angle is determined as formerly.

The program will analyze the viewshed only within these given azimuth angles.

The solar azimuth angle is the azimuth angle of the sun.
