The angle error equations derived to this point have reflected only the error performance due to thermal noise effects. However, angle-of-arrival performance can be affected by various sources of error other than thermal noise. In this chapter, we focus on errors that affect angle accuracy as opposed to angle precision. Because an interferometer determines angle-of-arrival from the output of phase or voltage from two antennas, the sensitivity of angle measurement to errors can be significant.
