The optical system initially delivered to JPL for solar simulation in the 25-foot space chamber included stainless steel mirrors in three positions.
Modified root-mean-square computer program used to evaluate distortion of reflective surface of paraboloidal antenna - Deep Space Instrumentation Facility /DSIF/
Simple models for the patterns as well as their cumulative gain probability and probability density functions of the Deep Space Network antennas are developed. These are needed for the study and evaluation of interference from unwanted sources such as the emerging terrestrial system, High Density Fixed Service, with the Ka-band receiving antenna systems in Goldstone Station of the Deep Space Network.

The microwave antenna holography imaging technique has progressed considerably in recent.
We present a method of synthesizing a correcting.
This paper discusses the fabrication considerations and proposed testing concepts related to a large twelve meter, graphite-epoxy space truss that is being developed to provide support of the primary mirror system for the Beam Transmission Optical System (BTOS).

We report on a comparative study of optical performance of gold films deposited by resistive and e-beam evaporation, including measurements of the scattering from the coated surfaces. The effects of oxygen bombardment and titanium under-layer on optical properties and adhesion were evaluated. The influence of surface preparation on the optical properties was examined also.

The Microwave Limb Sounder (MLS) is a limb-sounding radiometer sensing emissions in the millimeter and sub-millimeter range.
This paper is a summary of the work presented in the video tape demonstrating the integrated modeling capabilities that exist in an analytical tool being developed at JPL called IMOS (Integrated Modeling of Advanced Optical Systems).
It is the purpose of this paper to demonstrate that the typical approach based on the far field pattern of the feed would result into erroneous result and special care must be exercised to obtain the correct result.
