Search and rescue emergency locating transmitter detection/location procedure via TIROS satellite
Abstract
A procedure is described which works effectively to detect and locate emergency locating transmitters (ELTs) and emergency position indicating radio beacons (EPIRBs) in a multisignal environment. Using data generated from several manufactured ELTs with diverse superimposed Doppler curves, as many as 9 simultaneous ELTs can be detected and located at a variety of signal strengths. It is noted that average position errors of 10 km are attainable today at signal power to noise spectral density ratios as low as 17 dB-Hz.
