<p>The communication system is normally used in a radar beacon system for surveillance aircraft in a given geographic area. The communication system includes a number of omnidirectional receivers, each receiving the aircraft squits (transmissions) and developing from them a data string, indicative of a message in the aircraft squit, and a corresp. confidence string indicative of the reliability of the developed data string. The strings are transmitted from the receivers to the master data processor via a data communication link. The master data processor processes the strings by performing a bit-by-bit comparison of the received data strings and corresp. confidence strings, so as to develop a corrected data string which minimizes the use of data bits from the data strings received over the data communication link that are indicated by the corresp. confidence strings as having a low reliability.</p> |
