The invention belongs to the technical field of
civil aviation safety guarantee, and particularly relates to an aircraft emergency
distress signal monitoring system and monitoring method. The
monitoring system comprises a double-frequency
signal monitoring device, an information comprehensive
processing device and an alarm
display device, wherein the double-frequency
signal monitoring device can synchronously obtain two kinds of emergency signals and carry out corresponding
processing such as decoding and preliminary judgment on the position of an involved aircraft; the information comprehensive
processing device can correspondingly
process information transmitted by the double-frequency
signal monitoring device to obtain information such as the position and the identity of the involved aircraft; and the alarm
display device can be used for preprocessing data transmitted by the information comprehensive processing device, including displaying alarm information. According to the aircraft emergency
distress signal monitoring system and monitoring method, a localization technical means is provided, all-day real-time monitoring of the emergency signals is realized, the operation
weakness of the existing Cospas-Sarsat in a specific scene is effectively supplemented, and the
signal acquisition capability of
weak signal analysis error codes or incapability of receiving analysis in anelectromagnetic interference environment is improved.
