Surface Contour Radar Remote Sensing of Waves

Directional Spectra from Air- and Spaceborne Radar

Real-Time Rainfall Monitoring-Prediction System
During a 4-year period (1975-1979), a comprehensive hydrometeorological research program was carried out in the Chicago metropolitan area to develop better methods of utilizing meterorological...

Torsional Vibration Tests on Embedded Footings
Torsional vibrations are of common occurrence in foundations of structures subjected to eccentric loading in a horizontal plane. Foundations of radar and communication antennae and certain...

Airborne Laser Acquisition of Cross-Section Data

Remote Sensing and Mine Subsidence
Several types of remote sensor impagery was evaluated for identifying and mapping surface subsidence resulting from underground coal mining in the Northern Anthracite Coal Basin of Pennsylvania....

Hydrographic Surveying Turns to Electronics
Traditional technique for measuring water depth is to use a lead-weighted line. The tag line, stretched along the water surface so soundings are made in orderly fashion, can be dangerous....

Channel Siltation Determined with Side-Scan Radar
Of the new electronic means to measure water depth, side-scan sonar is unusual in that it gives not just a cross-section of the bottom but a semi-3-D picture of the bottom surface. Experienced...

Plastic Tower Solves Radar Interference
A new nonmetallic tower section has been designed to eliminate major rador interference problems caused by a steel Radar Microwave Link tower. The replacement section is composed of a...

Weather Modification for Use in High Plains
The users decision process on whether or not to utilize weather modification is not the same as the decision process involved in a scientific experiment. A decision to use weather modification...

Status of Ground-Probing Radar and Some Recent Experience

Subsurface Video Pulse Radars

Continuous Subsurface Profiling by Impulse Radar

Performance of Foundation for Altair Radar
The foundation for the ALTAIR antenna is a ring beam with a diameter of 118 ft, founded upon coral sand. Loads are applied to the foundation at four points; these points move around the...

Applications of Airborne Remote Sensing Technology
Aerial photography has been used for nearly a century. Recent developments in aerial photography, such as color film, color infrared film, and multiband photographic systems, have greatly...

Arecibo Radar-Radio Telescope - Design and Construction
The design and construction of the radar-radio telescope at the Arecibo Ionospheric Observatory is described. The fixed-dish spherical reflector has an 870-ft radius and a 1,000-ft diameter....

An Operational Look at Airport Design
The increase in aircraft speeds and operations led to serious problems in the control of airport traffic. The traffic controller has been subjected to a steadily increasing work load,...

Wind-Induced Vibrations in Antenna Members
Results of wind-tunnel tests of wind-induced vibrations in circular aluminum tubular members of large radar antenna space frames; curve for von Karman lift coefficient and semi-empirical...

Airport Master Planning: New Developments in Terminal Air Traffic Control (Increasing Airport Capacity An ASCE-AOC Joint Conference 1961)
Four years of experience of Airways Modernization Board in developing comprehensive program of inter-related projects for solution of air traffic control problem on total system basis;...

Timber Piles in Permafrost at Alaskan Radar Station
