Antenna evaluation study for the shuttle multispectral radar, phase 3

The principal objectives of Phase III were: (1) to continue simulations of the effects of excitation errors in the performance of a planar array antenna, (2) to apply this model specifically, to the SIR-A antenna, (3) to support measurements of the SIR-A antenna at JPL by quick-turnaround analyses of the SIR-A antenna under a variety of conditions encountered at the JPL West Mesa Antenna Range, and (4) to document fully all software developed for NASA Johnson Space Center (JSC) during Phases I, II, and III.
