1. Activate the sart
2. Mount it as high as possible when in lifeboat/liferaft
3. Wait for audible alert and flashing lamp to be activated automatically (this means that a searching radar is in vicinity). Now it's time to pick-up your portable VHF ch16
and start calling MAYDAY
Enjoy

On a military map it can stand for Secondary Surveillance Radar, Surface Search Radar, Search & Rescue Region, or Soviet Socialist Republic.
transponder/radar
Secondary radar system are known as "Interrogator/Transponders" and are cooperative radar systems. The Interrogator transmits a pulse pattern that signals the kind of response they are looking for transponders that receive it. The transponder replies with a pulse pattern on a different frequency. Transponders can also carrier coded information that give more then just there position. Most typical transponder system is associated with Air Traffic Control Radar. Air Traffic Control systems integrate the primary radar return (non-cooperative return) with the position and coded data from the secondary radar (cooperative return) that will also provide flight information like Squawk code (a Unique ID) altitudes speed position etc. The maritime equivalent has three equivalents SART (Search and Rescue Transponder), Racon Buoys (Navigation transponders that respond to maritime radar pulse width) and a systems that is not really radar but is VHF transmission and is called AIS (Automatic Identification System) but perform similar information to the ATC system. However when the term Secondary Radar is used it almost always means ATC Interrogator Transponder system or the military version system.

That rather depends in which context you mean ! When I first saw this question - the transponder I immediately thought of - is the kind that's built-in to an aircraft. An aircraft transponder is a small box of electronics, that transmits a constant stream of data - including the plane's identity, height, speed and radar heading. The control tower sees the data alongside a corresponding 'blip' on the radar screen.
An ATC transponder, or Air Traffic Control transponder, is an electronic device installed in aircraft that emits a unique identification signal in response to radar interrogations from air traffic control. It helps enhance situational awareness by enabling radar systems to track the aircraft's position, altitude, and speed. The transponder can also provide additional information, such as emergency codes, which assist controllers in managing air traffic safely and efficiently.

As of 2002, it is illegal to operate a radar detector on any U.S. military base.
Minnesota Radar and Laser Jammer laws Radar laser detectors are legal to own and operate in passenger vehicles in the state of Minnesota. Currently the only state that it is illegal to operate a radar detector is Virginia and Washington D.C. Laser jammers are illegal to operate in the states of: Nebraska, Minnesota, Utah, California, Oklahoma, Virginia, Colorado and Washington DC. Radar jammers are illegal to own and/or operate in all 50 states per the Federal Communications Commission. Radar detectors are also illegal in commercial vehicles weighing over 10,000 pounds in all fifty states, per Title 49 Transportation Act. Radar detectors are also illegal to operate on any military base.
Radar can operate at frequencies as high as the terahertz range, which is typically between 300 GHz and 3 THz. These high frequencies allow for higher resolution imaging and detection capabilities compared to lower frequency radar systems.
Basically there are no physical limitations of wavelength where a RADAR unit may operate, thereby it can operate practically on any wavelength from ELF (extremely low frequency) where wavelength can be as high as several hundreds kilometers or in Optical band like Laser RADAR (LADAR) who have wavelength of some microns . The limitations of RADAR operating wavelength is in their geometrical size of devices (transmitters, antennas and Receivers) required to produce such wavelength and their utilization . The following list is typical wavelength used by RADAR applications Search and Early Warning RADAR : >1- 10cm wavelength (HF- C band) Target Tracking RADAR : <10 cm Wavelength (C-band till milimmetric waveband) hope this helps
Radar the bat was "born" in a rescue and education wildlife center in Queensland, Australia. Officially, Radar was born in captivity and he is a Grey-headed flying fox, which is a species native to Australia.
