The invention relates to a multi-functional S-mode secondary radar test bench. The test bench comprises a switching sub unit, a transmit-receive sub unit, a digital processing sub unit, and a maintenance display device. The switching sub unit and the transmit-receive sub unit carry out bidirectional communication; and the transmit-receive sub unit and the digital processing sub unit carry out bidirectional communication. An output terminal of the digital processing sub unit is respectively connected with input terminals of a synchronous serial server and the maintenance display device; and an output terminal of a GPS / Beidou dual-mode server is connected with an input terminal of the digital processing sub unit. In addition, the invention also discloses a test method of a multi-functional S-mode secondary radar test bench. According to the invention, when electronic equipment uses the S-mode secondary radar product fully, the technical state verification of the radar replaceable unit can be realized under the circumstances that no extra instrument equipment is increased; and the technical state of the replaceable unit and the system function integrity can be verified.
Description
technical field [0001] The invention relates to the technical field of air traffic control monitoring, in particular to a multifunctional S-mode secondary radar test bench and a test method thereof. Background technique [0002] Mode S secondary radar provides enhanced monitoring and communication capabilities for the air traffic control automation system, which can effectively improve the working efficiency of secondary radar. At present, S-mode secondary radar has become the mainstream product of secondary radar. Equipping a special test bench for secondary radar is one of the basic measures for users to improve equipment maintenance and support capabilities. [0003] There are currently two types of radar test benches, one is a test bench for radar replaceable unit maintenance, and the other is a test bench for radar system technical state verification tests. The test bench for radar replaceable unit maintenance can only be used for fault diagnosis and maintenance of rep...
