Problems solved by technology

[0004] The purpose of the present invention is to provide a cooperative inquiry method for multiple local S-mode secondary surveillance radar stations, so that it can effectively reduce the number of all-call inquiries and responses, and further reduce the probability of synchronous crosstalk to solve the problem of dense deployment in local areas. When S-mode secondary radar, ask technical questions about code tension

Embodiment Construction

[0021] see figure 1 , figure 2 It can be seen that in the prior art, when a plurality of local S-mode radar stations work independently, the same interrogator code is configured, and because of the locking function of the transponder, only one radar station can receive the all-call response of the transponder, and Obtain the address code of the transponder, and complete the monitoring of the target within the selected interrogation period; if different interrogator codes are configured, the target will respond to all all-call inquiries within the common coverage area, and it is easy to generate signal gaps. interference. There are two situations as follows:

[0022] 1. When the query code is sufficient:

[0023] figure 1 It shows the situation when two ground radar stations work independently with different interrogation codes. After the target enters the surveillance range of radar station 1 at time T1, it receives an all-call interrogation signal from radar station 1,...

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of civil aviation control and radar surveillance, in particular to a cooperative inquiry method of multiple local S-mode secondary surveillance radar stations related to the deployment of S-mode secondary surveillance radar stations in the civil aviation field. Background technique [0002] Air traffic control secondary surveillance radar (SSR: Secondary Surveillance Radar) is an important part of the air traffic control system (ATC: Air Traffic Control), and it is a ground sensor that monitors the flight path and status of aircraft. The traditional SSR system adopts the A / C working mode. The International Civil Aviation Organization (ICAO) proposed S-mode technology to solve the code capacity limitation, synchronous crosstalk and asynchronous interference of the conventional A / C mode SSR. s solution. S-mode secondary radar can more effectively improve the current radar control capability, and provide a pow...
