toisiolähettimet
Toisiolähettimet, known in English as transponders, are electronic devices that emit a predetermined response when they receive a specific radio or radar signal. The term is a portmanteau of "transmitter" and "responder." Essentially, a toisiolähetin acts as an automated signal relay. When interrogated by a signal from a radar or other interrogation source, it transmits back a unique coded signal. This coded signal allows the interrogator to identify and track the toisiolähetin, and by extension, the object or platform it is attached to.
The primary function of toisiolähettimet is to enhance the detectability and identification of aircraft, ships, and
The signals transmitted by toisiolähettimet can vary in complexity. Simple toisiolähettimet might only transmit a static
