Description

Technical Field

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

[0002] Traditional airborne weather radar systems typically utilize a single-array architecture driven by a servo mechanism. The radar array is located at the nose of the aircraft, providing real-time weather data in the airspace ahead of the aircraft. As stealth aircraft's RCS (Radar Cross Section) decreases, weather sensors and other components contribute more and more to the overall aircraft, rendering single-array weather radar systems unable to meet stealth performance requirements.

[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 this application is to provide a stealth platform dual-array weather detection method and system to solve or alleviate at least one problem in the background technology.

[0005] The technical solution of this application is: a stealth platform dual-array weather detection method, comprising:

[0006] S10, a left antenna unit and a right antenna unit are respectively provided 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 for the left weather, and simultaneously 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 for the right weather, and simultaneously 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 for the front weather, and simultaneously 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 embodiment 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-array weather detection system for implementing any of the stealth platform dual-array weather detection methods described above, comprising: a left antenna unit, a right antenna unit, a receiving processing unit, and an integrated 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;

[0014] 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, wherein 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.

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 stealth platform dual-array weather detection method and system.

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

[0026] S10, a left antenna unit and a right antenna unit are respectively provided 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 for the left weather, and simultaneously 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 for the right weather, and simultaneously 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 for the front weather, and simultaneously 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 and 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 and 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 and processing unit, and is used to perform imaging processing on the breath detection data processed by the receiving and 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 a wired or wireless method.

[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 The figures show a single-array RCS simulation curve and a dual-array RCS simulation curve provided in one embodiment of the present application. As can be seen from the figure, the RCS is relatively large when the single-array meteorological detection system is at 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 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, 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 description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
