Description

Technical Field

[0001] The present application belongs to the field of meteorological detection for stealth aircraft, and in particular, relates to a dual-array meteorological detection method and system for a stealth platform. Background Art

[0002] Traditional airborne weather detection radar systems generally use a single-array architecture driven by a servo mechanism. The radar array is arranged at the nose of the aircraft to detect the weather in a certain airspace in front of the aircraft in real time. As the RCS (radar cross section) of stealth aircraft becomes smaller and smaller, weather detection sensors contribute more and more to the entire aircraft, resulting in the single-array weather radar system being unable to meet the requirements of stealth performance.

[0003] In view of the above reasons, under the premise of meeting the meteorological detection performance, a dual-array meteorological detection system or architecture is needed to improve the stealth performance of the sensor. Summary of the invention

[0004] The purpose of the present application is to provide a dual-array meteorological detection method and system for a stealth platform to solve or alleviate at least one problem in the background technology.

[0005] The technical solution of the present application is: a stealth platform dual-front meteorological detection method, comprising:

[0006] S10, a left antenna unit and a right antenna unit are respectively arranged on both sides of the nose of the stealth platform aircraft, and the left antenna unit and the right antenna unit are conformal to the shape of the nose;

[0007] S20, when it is necessary to detect the weather on the left side of the stealth platform aircraft, control the left antenna unit to transmit a detection beam to the left weather, and at the same time receive the returned weather detection data through the left antenna unit; when it is necessary to detect the weather on the right side of the stealth platform aircraft, control the right antenna unit to transmit a detection beam to the right weather, and at the same time receive the returned weather detection data through the right antenna unit; when it is necessary to detect the weather in front of the stealth platform aircraft, control the left antenna unit and / or the right antenna unit to transmit a detection beam to the front weather, and at the same time receive the returned weather detection data through the left antenna unit and / or the right antenna unit;

[0008] S30, processing the returned meteorological detection data to obtain meteorological detection imaging results.

[0009] In an optional implementation manner of the present application, the left antenna unit and the right antenna unit perform signal synchronization of detection data in a wired or wireless manner.

[0010] In an optional implementation manner of the present application, the array areas of the left antenna unit and the right antenna unit are the same.

[0011] On the other hand, the present application provides a stealth platform dual-front weather detection system for implementing any of the stealth platform dual-front weather detection methods described above, comprising: a left antenna unit, a right antenna unit, a receiving processing unit and a comprehensive processing unit, wherein:

[0012] The left antenna unit and the right antenna unit are used to receive or send meteorological detection data, and the left antenna unit and the right antenna unit perform signal synchronization on the detection data;

[0013] The receiving and processing unit is connected to the left antenna unit and the right antenna unit respectively, and is used to process the meteorological detection data received by the left antenna unit and the right antenna unit;

Through the time-sharing use of the two arrays and the fusion of detection data in overlapping areas, while meeting the meteorological detection performance, it fully utilizes the scattering peak distribution of the stealth platform aircraft, overlaps the scattering peak of the meteorological detection array with the structural scattering peak, and hides it in the aircraft RCS non-assessment area, thereby minimizing the RCS mean of the meteorological sensor. This not only expands the range of meteorological detection, but also transfers the antenna scattering peak to the electromagnetic window of the carrier aircraft, effectively reducing the RCS of the antenna aperture and improving the stealth performance of the entire aircraft.

[0023] In order to make the purpose, technical solutions and advantages of the implementation of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below in conjunction with the drawings in the embodiments of this application.

[0024] In order to overcome the problem that the single-array weather radar system in the prior art cannot meet the stealth performance requirements, the present application proposes a dual-array weather detection method and system for a stealth platform.

[0025] The stealth platform dual-front meteorological detection method provided in this application includes:

[0026] S10, a left antenna unit and a right antenna unit are respectively arranged on both sides of the nose of the stealth platform aircraft, and the left antenna unit and the right antenna unit are conformal to the shape of the nose;

[0027] S20, when it is necessary to detect the weather on the left side of the stealth platform aircraft, control the left antenna unit to transmit a detection beam to the left weather, and at the same time receive the returned weather detection data through the left antenna unit; when it is necessary to detect the weather on the right side of the stealth platform aircraft, control the right antenna unit to transmit a detection beam to the right weather, and at the same time receive the returned weather detection data through the right antenna unit; when it is necessary to detect the weather in front of the stealth platform aircraft, control the left antenna unit and / or the right antenna unit to transmit a detection beam to the front weather, and at the same time receive the returned weather detection data through the left antenna unit and / or the right antenna unit;

[0028] S30, processing the returned meteorological detection data to obtain meteorological detection imaging results.

[0029] like Figure 1 and Figure 2 As shown in the present application, a stealth platform dual-array meteorological detection system for implementing the above-mentioned stealth platform dual-array meteorological detection method is provided. The detection system includes: a left antenna unit, a right antenna unit, a receiving processing unit and an integrated processing unit. The left antenna unit and the right antenna unit are used to receive or send meteorological detection data, and the left antenna unit and the right antenna unit perform signal synchronization on the detection data. The receiving processing unit is respectively connected to the left antenna unit and the right antenna unit, and is used to process the meteorological detection data received by the left antenna unit and the right antenna unit. The integrated processing unit is connected to the receiving processing unit, and is used to perform imaging processing on the breath detection data processed by the receiving processing unit. The left antenna unit and the right antenna unit are respectively arranged on both sides of the nose of the stealth platform aircraft, and are conformal to the shape of the nose.

[0030] In some embodiments of the present application, the left antenna unit and the right antenna unit may synchronize signals of meteorological detection data via wired or wireless means.

[0031] In some embodiments of the present application, the array area in the left antenna unit and the array area in the right antenna unit may be the same or different, but usually the array area in the left antenna unit and the array area in the right antenna unit are the same.

[0032] like Figure 3 and Figure 4 Shown are a single-array RCS simulation curve and a dual-array RCS simulation curve provided in an embodiment of the present application. It can be seen from the figure that the RCS is larger when the single-array meteorological detection system is near a heading angle of 0°, while the RCS is always at a low level in the dual-array meteorological detection system of the present application.

[0033] In view of the fact that the single-array meteorological detection system architecture at the nose contributes too much to the RCS of the stealth platform, this application adopts a dual-array meteorological detection architecture. Through the time-sharing use of the two arrays and the fusion of detection data in the overlapping area, while meeting the meteorological detection performance, it fully utilizes the scattering peak distribution of the stealth platform aircraft, overlaps the scattering peak of the meteorological detection array with the structural scattering peak, and hides it in the aircraft RCS non-assessment area, thereby minimizing the RCS mean of the meteorological sensor. It not only expands the range of meteorological detection, but also transfers the antenna scattering peak to the electromagnetic window of the carrier aircraft, effectively reducing the RCS of the antenna aperture and improving the stealth performance of the entire aircraft.

[0034] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
