 What is Synthetic Aperture Radar? -- Sandia National Laboratories
SAR systems take advantage of the long-range propagation characteristics of radar signals and the complex information processing capability of modern digital electronics to provide high resolution imagery.
A detailed description of the theory of operation of SAR is complex and beyond the scope of this document.
Since SARs are much lower in frequency than optical systems, even moderate SAR resolutions require an antenna physically larger than can be practically carried by an airborne platform: antenna lengths several hundred meters long are often required.

 SAR Records Encyclopedia Article @ LaunchBase.net (Launch Base)   (Site not responding. Last check: 2007-11-03)
SAR Records was a record company founded by soul music legend Sam Cooke in 1959.
The meaning of "SAR" has been disputed; it has been listed as "Sam and Alex Records" (J.W. Alexander was Cooke's business, song-writing associate, and friend) and also as "Sam, Alex, and Roy Records" (Roy being S.R. Crain, Cooke's mentor from his Soul Stirrers days, as well as his pop road manager).
The label was intended to be a place where Sam Cooke could expand his artistic abilities as a writer/producer and to give other struggling African-American artists a venue to record during the racially charged 1960's.

 The DLR Airborne SAR Project E-SAR
Today, airborne SAR forms a major subject in the institute, not only to show its technological feasibility, but to exploit its benefits to a range of applications, such as agriculture and forestry.
The decision to develop an airborne SAR system was initially taken to gain sufficient Know-how in SAR sensor design and data processing to support the space missions ERS-1 and SIR-C/X-SAR.
SAR interferometry and SAR polarimetry are new functional modes of the radar, which are on their way to be integrated during 1996.

 RF Exposure: SAR Standards and Test Methods   (Site not responding. Last check: 2007-11-03)
SAR is an index that quantifies the rate of energy absorption in biological tissue.
SAR is generally quoted as a figure averaged over a volume corresponding to either 1 g or 10 g of body tissue.

 sar(1): Collect, report, or save system ... - Linux man page
Without the -P flag, the sar command reports system-wide (global among all processors) statistics, which are calculated as averages for values expressed as percentages, and as sums otherwise.
Each record contains the hostname of the host where sar was run, the interval value (or -1 if not applicable), the sar timestamp in a form easily acceptable by most databases, and additional semicolon separated data fields as specified by other sar command line options.
The SELF keyword indicates that statistics are to be reported for the child processes of the sar process itself, whereas the ALL keyword indicates that statistics are to be reported for all the child processes of all the system processes.

 A brief description of SAR
The SAR sensor is mounted on an aircraft or a satellite, and is used to make a high-resolution image of the earth's surface.
SAR uses a wavelength of 1 cm to 1 m, while optical sensors use wavelengths near that of visible light, or 1 micron.
SAR systems generally have very long antennas; one of the longest one is on Radarsat, at 15 m.

 Search and Rescue Dogs
SAR dogs are employed in a variety of emergency circumstances, such as, urban and wilderness settings to locate missing persons, in situations following a disaster such as earthquake or hurricane, and following avalanche or drowning incidents.
The training of SAR dogs is a lengthy process initially (normally about two years), followed by a life-long commitment to build and maintain a level of confidence and experience necessary to keep the SAR team "mission-ready".
SAR work requires a great deal of time out of your life, in fact, it can become your life; it will cost you thousands of dollars in equipment, travel and training; once you are certified as 'mission ready', call-outs occur at inconvenient times and conditions during a search are likely uncomfortable.

 Verizon Wireless Radio Frequency Emissions
SAR is a measure of the rate of absorption of RF energy in the body.
Although the SAR is determined at the highest power level, the actual SAR value of a wireless phone while operating can be less than the reported SAR value.
This is because the SAR value may vary from call to call, depending on factors such as proximity to a cell site, the proximity of the phone to the body while in use, and the use of hands-free devices.

 International Convention on Maritime Search and Rescue, 1979
Parties are encouraged to enter into SAR agreements with neighbouring States involving the establishment of SAR regions, the pooling of facilities, establishment of common procedures, training and liaison visits.
The SAR Convention allowed for amendments to the technical Annex to be adopted by a Conference of STCW Parties or by IMO's Maritime Safety Committee, expanded to include all Contracting Parties, some of whom may not be members of the Organization.
It was designed to help Governments to implement the SAR Convention and provided guidelines rather than requirements for a common maritime search and rescue policy, encouraging all coastal States to develop their organizations on similar lines and enabling adjacent States to co-operate and provide mutual assistance.

 Parabolic Stop and Reverse at Trade10.com- The science of trading market momentum for stocks, options, futures and ...
When price penetrates the SAR a new calculation is started taking the other side of the market with an initial setting that again allows a certain amount of initial volatility if the trend is slow to get underway.
The SAR can be used to set stop orders later in the trend or as a conformational tool in confirming the trend.
Some traders may consider the SAR for both entry and exit signals but some caution should be applied to this approach as whipsaw losses can mount during a time period of multiple short trend reversals over a short time period.
