The invention provides a synergic inquiring method for local multiple S-mode secondary monitoring
radar stations, which is relevant to the distribution of S-mode secondary monitoring
radar stations in the field of
civil aviation, and relates to the technical field of
civil aviation air traffic control and
radar monitoring. In the method, at least two or more adjacent S-mode radar stations construct a cluster, the same inquiring code is assigned to the radar stations in the cluster, the cluster radar stations are connected with each other through a
communication link, the monitoring target of each radar
station in the cluster is classified, and target state information is subjected to synergic
processing, so that synergic information can be communicated in time during synergic work; a plurality of radar stations with the same inquiring codes work synergistically, and selective inquiring of general-calling-free inquiring is realized; and the technical problem of incapability of monitoring a target caused by locking of a
machine-carried response
machine since the inquiring codes of the radar stations are the same is solved, the synergic monitoring of a plurality of radar stations is realized, and risks caused by insufficient inquiring codes is lowered.
