Time-Shifted PN Codes for CW LIDAR, RADAR, and SONAR

Algorithm eliminates channel interference and artifacts from lidar return signals.NASA’s Langley Research Center has developed a waveform processing technique to eliminate signal noise resulting from sources of interference (scatterers) that can degrade continuous wave (CW) lidar return data. The algorithm was developed to enable CW lidar measurement of atmospheric gas concentrations as part of NASA’s Active Sensing of CO2 Emissions over Nights, Days, and Seasons (ASCENDS) program, but can be used to test any chemical species, such as poison gas or other trace elements in the atmosphere. The algorithm demonstrated reduction in interference resulting from thin cloud layers and other scatterers. The improvement holds the potential for significant advancement of CW lidar systems that are less expensive, of simpler design, and can be operated at higher average power than pulsed lidar systems.

Data Informatics Infrastructure for the Megacities Carbon Project

With the goal of assessing the anthropogenic carbon-emission impact of urban centers on local and global climates, the Megacities Carbon Project has been building carbon-monitoring capabilities for the past two years around the Los Angeles metropolitan area as a pilot effort. Hundreds of megabytes of data are generated daily and distributed among data centers local to the sensor networks involved. These remotely generated data are then aggregated into a centralized data infrastructure located at the Jet Propulsion Laboratory (JPL) to provide collaboration opportunities on the data as well as generate refined data products through centralized data processing pipelines.

Airborne Elastic Backscatter and Raman Polychromator for Ash Detection

Volcanic ash is a significant hazard to aircraft engines and electronics. It has caused damage to unwary aircraft and disrupted air travel for thousands of travelers, costing millions of dollars. The small, jagged fragments of rocks, minerals, and volcanic glass that constitute volcanic ash are about the size of sand and silt. Volcanic ash is hard, does not dissolve in water, is extremely abrasive and corrosive, and conducts electricity when wet. The upper winds transport the particles away to eventual dispersal in an ash cloud. Ash clouds typically form above 20,000 feet, but the lower limit of the initial cloud depends on both the height of the volcanic vent and the vigor with which material is ejected from it.

Editor's Choice: January 2017

The Convective Heating Improvement for Emergency Fire Shelters (CHIEFS) material can improve the performance of emergency fire shelters for wildland firefighters. The material is based on technology developed for planetary exploration mission heat shields. Fire shelters are the last resort for firefighters trapped by wildfires that block their escape routes. The CHIEFS system can withstand temperatures to 3000 °F. Click here to find out more.

NASA Tests New Jet Engine Design

NASA is helping the aircraft industry increase fuel efficiency with a new engine design. In its 8 × 6-foot wind tunnel, Glenn Research Center engineers are testing a new fan and inlet design, called a propulsor, that could increase fuel efficiency by four to eight percent more than the advanced engine designs airlines are beginning to use.

New Stamping Technique Enables Printable Electronics

The carbon nanotube stamp can print electronic inks onto rigid and flexible surfaces. (Sanha Kim and Dhanushkodi Mariappan) The next time you place your coffee order, imagine slapping onto your to-go cup a sticker that acts as an electronic decal, letting you know the precise temperature of your coffee. Engineers at MIT have invented a fast, precise printing process that may make such electronic surfaces an inexpensive reality. The stamp is made from forests of carbon nanotubes and can print electronic inks onto rigid and flexible surfaces. The stamping process should be able to print transistors small enough to control individual pixels in high-resolution displays and touchscreens. It could also offer a relatively cheap, fast way to manufacture electronic surfaces for as-yet-unknown applications.
