everything RF

The topics listed below were selected based on their relevance to a wide spectrum of RF Cafe visitors. There is a good chance that if you are reading this, you are an engineer, physicist, chemist, research scientist, student, or even a hobbyist whose primary vocation (what pays the bills) is something not remotely related to science. Please let me know if you think there is something else that should be added.

While performing searches for various engineering topics, it is often difficult to locate the desired material. That is because many documents are either buried deep within the results, or they are never indexed by the search engines in the first place. Government websites are good sources of information, but it typically takes doing multiple hit-and-miss searches within the website's database to find information. As time permits, I have been re-publishing documents that I find so that the search engines will index them.

Unless otherwise marked, U.S. government documents may be freely copied so long as the content is not altered from the original. Warning: Some of these documents have been processed with optical character recognition (OCR) software and might contain errors.

What Is Radar?


On a whim, I decided to search for declassified documents on the subject of radar, radio, and related communications subjects. Actually finding relevant content takes a bit of work, so I am going to spend some time locating and reproducing some of them here on RF Cafe. Having a repository of readily available reports will make future research a little easier. Government documents, unless otherwise marked, are available for reprint so long as the content is unaltered. Warning: These documents have been processed with optical character recognition (OCR) software and might contain errors.
