Underwater Electroacoustic Transducers. Dennis Stansfield. This reprint is a practical handbook for users and designers of underwater transducers. It has been an authoritative text in the field since first published by the Bath University Press in 1991. Design methods are illustrated by concentrating on the design of piezoelectric transducers in the 2 – 20 kHz range, most commonly used in sonar systems. Designs for frequencies below this range are also discussed. Treatment is down-to-earth and avoids complex mathematics. Topics include the role of the transducer as an element of the complete system; wide bandwidth, high power transmitter applications; wide band hydrophones; characteristics of piezoelectric and magnetostrictive materials; and transducer testing. For the user, the wide range of topics and practical approach of the book help him to identify the most important features of the requirement and assist him in drawing up realistic specifications. For the designer, the book describes the necessary theoretical and practical aspects involved in developing a transducer to most effectively suit the application and it discusses the main features of the various types of designs.

Matched Field Processing for Underwater Acoustics. Alexandra Tolstoy. Published by the World Scientific Publishing Company in 1993. The author was with the Naval Research Laboratory. Matched Field Processing is the process of cross-correlation of a measured field with a modeled, predicted or replica field to determine a set of input parameters that yield the highest correlation. Typically, input parameters in to a selected sound propagation model would include candidate range, bearing and depth of a source relative to the receiving array. The sound propagation model might be defined by environmental data such as sound speed profiles, bottom and surface conditions, tides, and composition of the water. The matched field processing (MFP) would be employed to determine the location of the source – the exact relative range, bearing and depth of the source. This book is for scientists and engineers who are familiarizing themselves with MFP and those in need of detailed information about the process. The first two chapters address a brief history of MFP and discuss other types of processors used in underwater acoustics. The third chapter discusses where errors in MFP solutions occur due to errors in the propagation model. Chapter 4 gives the reader a familiarity of how linear and minimum variance processors perform under a wide range of conditions. And the last chapter addresses broadband processing, source movement, and multiple sources.

Radar and Radar Signal Processing Systems Are Making Flying The Friendly Skies Safer From Bird Strikes

Radar and advanced radar signal processing technology can help make flying safer by avoiding bird strikes.

In the wake of the emergency crash landing of US Airways Flight 1549 in New York’s Hudson River on January 2009, the National Transportation Safety Board is conducting a hearing on implementing currently available avian radar technology to airports throughout the United States. The avian radar industry urges the Federal Aviation Administration (FAA) to make the friendly skies a safer place by immediately deploying commercially-available avian radar systems to our nation’s airports. Bird strikes pose a serious threat to aviation safety. According to the FAA “there were more than 7,400 bird strikes in the United States in 2007, including 110 that caused substantial damage to aircraft.”

According to Dr. Tim J. Nohara, President of Accipiter Radar “avian radar can help mitigate bird hazards where they are most likely to occur around the airport. Real-time monitoring and alerting of approaching flocks of birds helps wildlife control personnel better manage bird hazards.”

In 2006, the FAA began evaluating the avian radar program Accipiter Avian Radar to assess if the use of commercial avian radar at airports would be justified, and would not compromise safety and would be compatible with existing wildlife control operations. The FAA contends that due to the unusual circumstance of the birdstrike current avian radar systems could not have prevented the crash of flight 1549. Flight 1549 was an unusual in that it was a high altitude strike (2800 feet) and did not occur in the immediate vicinity of the airport.

Developers within the avian radar industry, however, assert that current avian radar technology could have prevented the crash. Gary W. Andrews, CEO of DeTect (a industry leading developer of avian radar systems) stated that although some avian radar systems do not have long-range detection capabilities systems, others such as MERLIN Aircraft Birdstrike Avoidance Radar can reliably detect and track bird flocks at a range of up to 8 miles.

Andrew’s contends that MERLIN Radar system has been successfully used throughout the globe for “birdstrike risk detection, tracking and alerting at commercial airports, military airfields, and space launch facilities, with real-time bird activity displays used by airfield managers, bird control staff and air traffic controllers”
Courses in radar and radar signal processing are now becoming available to the public. The Applied Technology Institute of Riva, MD., will offer a three-day course in July 13-15 in Laurel,MD. ATI’s Radar Signal Analysis and Processing using MATLAB course explores algorithms for signal detection, false alarms, tracking techniques and systems performance equations.

Radar Signal Analysis and Processing using MATLAB course is being held July 13-15, 2009 in Laurel, Maryland, in the Washington DC area.

Workers For The U.S. Satellite Industry

I thought that this was interesting:

by Marion Blakey, President and CEO
Aerospace Industries Association

Photo 1
The U.S. satellite industry has a great deal to worry about these days ­— lost opportunities due to outdated export control rules, global competition from more and more countries every day, the various technical challenges of providing new services — but there’s another issue out there affecting the entire aerospace industry that demands attention in the satellite sector — a looming workforce crisis.

The U.S. aerospace industry workforce is currently dominated by aging workers — baby boomers who were enthralled with space travel and answered our nation’s call to win the Space Race and put Americans on the moon. Today, nearly 60 percent of aerospace workers were age 45 or older in 2007, with retirement eligibility either imminent or already reached.

There is a growing need to replace these experienced workers, especially the engineer talent pool, with capable new talent to ensure that the United States continues to be the world’s leader in satellite technology and other important aerospace applications. But there are not sufficient numbers of young people studying Science, Technology, Engineering and Mathematics — the STEM disciplines — that would put them on the path to enter aerospace careers and replace our retiring workers.

There is very strong competition for our nation’s brightest math- and science-oriented students. Aerospace companies are forced to share talent with a variety of high-tech industries that were not even around when baby boomers were selecting their careers. For example, more than half of those who graduate with bachelor’s degrees in engineering go into totally unrelated fields for employment. And the numbers earning advanced degrees in STEM subject areas lag other fields by huge margins.
