Abstract
A monopulse secondary surveillance radar is configured to integrate replies to active interrogations and passive squitter reception into a single surveillance system, and includes: a three-channel antenna arrangement; a redundant ADS-B antenna arrangement including a first and second omnidirectional ADS-B antenna, each having a low noise amplifier, and each being integrated with a GPS antenna; and a pair of redundant four-channel interrogators. The three-channel antenna arrangement is configured to transmit interrogations, and to receive corresponding replies from an aircraft transponder. The first ADS-B antenna is coupled to a first of the pair of redundant four-channel interrogators, and the second ADS-B antenna is coupled to a second of said pair of redundant four-channel interrogators, for the monopulse secondary surveillance radar to provide real-time passive detection of ADS-B-equipped aircraft and active radar detection of aircraft to each of the pair of redundant four-channel interrogators.
