Description

Technical Field

[0001] The present invention relates to the technical field of answering device detection, and in particular to an answering device detection method and device for evaluating a surrounding complex interrogation environment. Background Art

[0002] With the rapid development of the aviation industry, the number of civil aircraft is increasing, and the density of air traffic is gradually increasing. In order to ensure the safety of civil aviation flights, the deployment of civil secondary radars is becoming more and more intensive. The flight training of military aircraft is becoming more and more frequent, which also requires more military secondary radars to ensure the smooth implementation of training tasks. At present, the interrogation signals radiated by military and civil secondary radars with different purposes and different power coverage are intricate, and the complex interrogation environment will in turn affect the aircraft in the airspace.

[0003] For civil aviation systems, it is necessary to evaluate the complex interrogation environment and take corresponding measures based on the evaluation results; for military systems, it is necessary to detect electromagnetic signals such as interrogations in the airspace, obtain the activity status of various secondary radars, evaluate the detected information, and provide support for subsequent actions.

[0004] The assessment of the electromagnetic environment such as interrogation comes from the collection of operating parameters of each secondary radar in the assessment area on the one hand, and from the acquisition of detection information by the air detection system on the other.

[0005] The details are as follows:

[0006] 1. Collect the relevant working parameters of each secondary radar in the evaluation area (inquiry cycle, inquiry mode, antenna rotation speed, working position environment, etc.), simulate the radiation of the inquiry signal in the area, and then evaluate the results. However, the working parameters of the secondary radar in the real environment change in real time. For example, some military secondary radars are mobile (ground mobile, airborne mobile, etc.) and the working time is difficult to determine, and many working parameters are unknown. The simulation environment may be very different from the real environment and cannot be used as a basis for evaluation.

[0007] 2. Install special interrogation signal detection equipment on the aircraft, and detect the interrogation signal in the airspace to achieve the purpose of evaluating the interrogation environment in the airspace. However, this method requires the addition of special detection equipment, which is expensive and is also restricted by the installation space of the aircraft; and this method is limited by the flight route and flight time. The information evaluated is only the detection information of a specific space and a specific period of time, which is still a certain gap from the real environment, and the credibility of its evaluation results is not particularly high.

[0078] Different secondary radars are deployed more and more densely and intertwined with each other, and the radiation of interrogation signals of various radars is complicated. The transponder is a special device that receives interrogation signals and makes different responses according to the type of interrogation signal. While receiving the interrogation and making responses, it can also record and save the changes of the detected interrogation signal. The detection results are transmitted to the ground station in real time for analysis and evaluation through other means of the carrier aircraft (such as data link communication, etc.), or the detection data is recorded, and the recorded data is read back for analysis after the carrier aircraft lands, so as to achieve the purpose of evaluating the complex interrogation environment in the corresponding airspace. Therefore, by adopting the above-mentioned transponder device detection method for evaluating the surrounding complex interrogation environment, it has the following advantages:

[0079] 1. The traditional method of evaluating the surrounding complex interrogation environment is to inspect and collect the working status information of the surrounding secondary radars, and then analyze and evaluate. This method is time-consuming and labor-intensive. The present invention can greatly reduce the labor cost and shorten the evaluation cycle.

[0080] 2. Military systems generally require special aircraft to be equipped with interrogation signal detection devices, and interrogation signals are detected on the applied special routes. The present invention can upgrade the software only on the transponder required by the aircraft, and the aircraft can perform signal detection during normal flight according to daily arrangements; the cost of modification is low, and the airspace resource occupation of the special route can be reduced, reducing the impact on military and civil aviation flights, and will not increase the workload of control personnel.

[0081] 3. The information collected is real-time, true and rich, and the evaluation results will be more accurate. Based on the evaluation results, the civil aviation system can adjust the parameters such as the interrogation cycle, interrogation mode and antenna rotation speed of the secondary radar in the airspace, and increase or decrease the transmission power to adjust the detection range. Based on the evaluation results, the military system can understand the complexity of the electromagnetic environment in the airspace, obtain the activities of various secondary radar targets, and provide intelligence support for subsequent combat missions.
