Abstract
The elevation effects on the azimuth error are geometric in nature and were evaluated to determine if they are needed in the azimuth determination and to calculate the magnitude and root mean square azimuth error. A simulation was done using three different angles 10°, 25°, and 45°. The simulation sweeps from 0° to 24° in azimuth angle, and the error is plotted in degrees. The results of the simulations are shown. The azimuth error is directly proportional to the elevation angle; the higher the angle the greater the error. Also, the azimuth error is directly proportional to the azimuth angle off interferometer boresight. This analysis was performed with a horizontal interferometer baseline with no pitch and roll.
