Book Description
PAVE PAWS is a phased-array warning system designed to detect and track sea-launched and intercontinental ballistic missiles operated on Cape Cod since 1979 by the U.S. Air Force Space Command. In 1979, the National Research Council issued two reports to address concerns from Cape Cod residents about the safety and possible health effects of the radiofrequency energy from the radar. Following up on the1979 report, the new report finds no evidence of adverse health effects to Cape Cod residents from long-term exposure to the PAVE PAWS radar. The report specifically investigated whether the PAVE PAWS radar might be responsible in part for the reported higher rates of certain cancers in the area, but concludes there is no increase in the total number of cancers or in specific cancers of the prostate, breast, lung, or colon due to radiation exposure from PAVE PAWS. The report did find in the scientific literature a few biological responses to radiofrequency exposures that were statistically significant. Such responses do not necessarily result in adverse health effects, but the report recommends additional studies to better discern the significance, if any, of those findings.

Book Description
Provides comments for the plans for Phase IV of the Air Force waveform characterization effort. This request stems from questions raised by the Committee during discussions with the Air Force relating to their Phase IV measurement plans. Specifically, the Air Force asked the committee to provide any comments, concerns, or questions related to the time-domain measurement effort, and suggest approaches to modeling the time-domain waveform to assist in the measurement effort.

Radar Principles for the Non-Specialist
Author: John C. ToomayPublisher: Springer Science & Business Media
ISBN: 9401169853
Category : Science
Languages : en
Pages : 254
Book Description
What This Book Is This book is about radar. It will teach you the essentials of radar, the underlying principles. It is not like an engineering handbook which pro vides detailed design equations without explaining either derivation or rationale. It is not like a graduate school textbook which may be abstruse and esoteric to the point of incomprehensibility. And it is not like an anthology of popular magazine articles which may be gaudy but superfi cial. It is an attempt to distill the very complex, rich technology of radar into its fundamentals, tying them to the laws of nature on one end and to the most modern and complex systems on the other. Who It's For If your work requires you to supervise or meet as coequals with radar systems engineers or designers, this book will allow you to understand them, to question them intelligently and perhaps to provide them with a perspective (a dispassionate yet competent view) that they lack. If you are trained in another discipline but have been made the man ager of a radar project or a system program that has one or more radars as sub-systems, this book will provide you with the tools you need, not only to give your team members confidence, but also to make a substantive technical contribution yourself.
A Strategy for Active Remote Sensing Amid Increased Demand for Radio Spectrum
Author: National Academies of Sciences, Engineering, and MedicinePublisher: National Academies Press
ISBN: 0309373085
Category : Science
Languages : en
Pages : 254
Book Description
Active remote sensing is the principal tool used to study and to predict short- and long-term changes in the environment of Earth - the atmosphere, the oceans and the land surfaces - as well as the near space environment of Earth. All of these measurements are essential to understanding terrestrial weather, climate change, space weather hazards, and threats from asteroids. Active remote sensing measurements are of inestimable benefit to society, as we pursue the development of a technological civilization that is economically viable, and seek to maintain the quality of our life. A Strategy for Active Remote Sensing Amid Increased Demand for Spectrum describes the threats, both current and future, to the effective use of the electromagnetic spectrum required for active remote sensing. This report offers specific recommendations for protecting and making effective use of the spectrum required for active remote sensing.
