Analysis of errors for uplink array of 34-m antennas for deep space applications

Although the technologies for large arrays of distributed reflector antennas with just downlink (receiving) capability have been well defined and proven for deep space applications, a similar architecture, i.e., the arraying of distributed reflector antennas for uplink (transmitting) applications has not been proven, tested, or built yet. In previous papers (Hurd, 2005) the need, feasibility, technology challenges and high-level system issues of a large array of reflector antennas with uplink capability for the future deep space network (DSN) were discussed. In particular, the primary design drivers, cost drivers, and technology challenges for uplink array phase calibration were addressed together with some preliminary test results with the 34-m antenna exciters. It is now of great interest to obtain the key requirements for the current Deep Space Network (DSN) 34-m antennas so that they can operate in an uplink array mode. The successful demonstration of the DSN 34-m antennas in uplink array mode serves as a prototype and a key milestone for the future large array development. In this paper, simulation and analysis of the current DSN 34-m antennas in an uplink array mode were discussed
