Thermal Response in Antenna Under Laser Irradiation
This investigation focuses on the thermal response of two objects under medium-intensity continuous-wave (CW) laser irradiation: (1) a homogeneous slab and (2) a complex electronic component,...

An Inflatable Antenna for Space-Based Low-Frequency Radio Astronomy
Antennas for a low-frequency orbiting radio telescope must have minimal problems in deployment, a directional beam, and a wide-angle scanning capability. Inflatable antennas with deposited...

Gravitational Wave Astronomy and the Lunar Ligo Concept
The preliminary proposal (LaFave and Wilson, 1993, 1992) for emplacing a modest LIGO [ Laser interferometer Gravitational Wave Observatory ] system on the Moon using unmanned robotic landers...

SALSA: A Lunar Submillimeter-Wavelength Array
A conceptual design is described for a lunar submillimeter-wavelength interferometer called SALSA, a Synthesis Array for Lunar Submillimeter Astronomy. The intent is to describe SALSA...

Concept for a Lunar Array for Very Low Frequency Radio Astronomy
We discuss the design considerations relevant to a very low frequency array, to be deployed on the lunar near side during an early expedition. Such an array would operate in the frequency...

Fully Nonlienar Models to Simulate Structural Response to Wind Loading
The paper summarizes some results of the analyses of two tall broadcasting towers, obtained by means of a specially developed numerical procedure taking into account all relevant nonlinear...

Wind Loads on Large Broadcasting Antennas: Records and Elaborations
Alternative estimations of the 50-year gust winds from the data available in typical Italian sites of broadcasting antennas are summarized and compared with the design winds suggested...

Design Wind Loads for Broadcasting Antennas from Short Time Records
Very useful would be procedures for the determination of the design wind load on the basis of short time records, of duration comparable with the preliminary and/or design phases, so that...

Utilization of Ground Penetrating Radar to Conduct Sediment Surveys of Frozen Reservoirs
The ground penetrating radar (GPR) system consisted of a control unit, antenna, recorder, a power supply on a sled towed by a snowmobile. A 120 Mhz antenna was utilized and gave excellent...

Concrete Rehabilitation Options and Solutions
This paper demonstrates the basic steps for a successful rehabilitation program using a case study of the rehabilitation work for the NASA/JPL 64-meter deep space communication antenna....

Big New Radio Telescope Array Listens in on Space
The world's most powerful radio telescope is so sensitive that it can detect a small CB rig operating on a distant planet. The Very Large Array (VLA) Radio Telescope Facility...
