Abstract
A necessary step in the design of a high-accuracy microwave antenna system is to establish the signal error budget due to structural, pointing, and environmental parameters. This report, the first of a series, deals with a unified approach in performing error budget analysis as applicable to ground-based microwave antennas of different size and operating frequency. A discussion of major error sources contributing to the resultant deviation in antenna boresighting in pointing and tracking modes and the derivation of the governing equations are presented. Two computer programs (SAMCON and EBAP) have been developed in-house, including the antenna servo-control program, as valuable tools in the error budget determination. A list of possible errors giving their relative contributions and levels is presented.
