The function of this millimeter-wave cloud detection radar 7 includes obtaining cloud target dynamic data.

[0025] In another specific embodiment of the above-mentioned UAV meteorological emergency detection system, the imaging system 2 can be selected as a visible light high-resolution digital imaging system, so that a large range of high-resolution images can be obtained from the air, providing a more comprehensive and accurate basis for emergency detection. Of course, other imaging systems can also be selected according to actual needs, which is not limited here. In a further embodiment, the above-mentioned meteorological radar 5 can preferably be a meteorological radar that uses C / L two bands for SAR imaging. Compared with ordinary optical sensors, this SAR imaging meteorological radar actively radiates electromagnetic waves and performs imaging through the scattering of electromagnetic waves by the target.

It has all-day and all-weather imaging detection capabilities, is not affected by weather and climate, has leaf cluster penetration ability and surface penetration ability, and can use electromagnetic wave polarization to achieve target classification.

In a further embodiment, the above-mentioned wind measurement laser radar 6 can be preferably mounted on the optoelectronic ball cabin of the drone body 1, and the above-mentioned millimeter wave cloud measurement radar 7 can be preferably mounted on the visible light CCD cabin of the drone body 1. Specifically, the drone body 1 used must meet the following requirements: there is no obstruction within ±90° in the forward direction of the nose and ±90° in the heading direction, and it can meet the simultaneous installation and use of the visible light high-resolution digital imaging system, weather radar type II and route weather detector, and meet the detection field requirements. There are no obstructions in the space below the belly position, and the maximum detection range of the belly load is within ±45°. It is not affected by the fuselage's own structure, adjacent loads, and external drop-down sounding pods. It can accommodate the simultaneous installation and use of two types of belly loads (wind laser radar, millimeter-wave cloud radar), nose loads, and external loads, meeting the detection field of view requirements. The video monitoring system is located on the belly and exposed, with the field of view facing the external attachment point and the field of view unobstructed, so the drop-down sounding pod can be observed. The drop-down sounding pod is located at the wing external attachment point, away from the fuselage and other loads, so it has no impact.

[0027] In another preferred embodiment of the above-mentioned UAV meteorological emergency detection system, it can also include a power supply component for supplying power to various loads on the UAV body 1. The loads mentioned here are the aforementioned imaging system 2, route meteorological detector 3, dropsonde system 4 and meteorological radar 5, etc. These loads are powered independently to ensure that they are not affected by other parts during operation. Specifically, the power supply component can be a battery or a fuel power generation system, which is not limited here.

[0028] In another preferred embodiment of the above-mentioned UAV meteorological emergency detection system, each load on the UAV body 1 is connected to the mission data recorder through the same type of universal interface unit and finally connected to the link. Figure 2 , Figure 2 The figure is a connection diagram of each component of the UAV meteorological emergency detection system. The UAV meteorological emergency detection system may include a power distribution box, a mission data recorder and a link. The power distribution box may be preferably connected to other loads through a 28V cable. The route meteorological detector 3 can be connected to the integrated navigation system through RS422, the visible light high-resolution digital imaging system 2 can be connected to the link through HD-SGI, the meteorological radar 5 can be connected to the universal interface unit and the mission data recorder through RS422, respectively, the wind laser radar is connected to the universal interface unit through RS422, the millimeter wave cloud radar RS422 and CameraLink are connected to the universal interface unit, the dropsonde system is connected to the universal interface unit through RS422, the integrated navigation system is connected to the mission recorder through 1553B, the universal interface unit is connected to the mission data recorder through 1394, and the mission data recorder is connected to the link through 1394. In this way, the power supply and communication cable connector models of each load are the same, and the loads in the same installation position can be replaced quickly through the same position replacement, thereby improving the reliability and scalability of the overall system. The transmission paths of the above-mentioned payload mission data can be as follows: route meteorological detector: payload-integrated navigation system-mission data recorder-link; meteorological radar type II: payload-general interface unit-mission data recorder-link; visible light high-resolution digital camera: payload-link; wind laser radar: payload-general interface unit-mission data recorder-link; millimeter wave cloud radar: payload-general interface unit-mission data recorder-link; dropsonde system: payload-general interface unit-mission data recorder-link. Different payloads under the same transmission conditions can be quickly replaced if the installation position allows. If there is a communication failure at one position, it can be replaced at other positions with the same communication status, making the payload safer to use.

[0029] In summary, the above scheme utilizes the characteristics of high-altitude UAVs, such as fast speed, maneuverability, and long flight time. It is equipped with flight line meteorological detectors, visible light high-resolution digital imaging systems, meteorological radar II, dropsonde systems, wind measurement lidars, millimeter-wave cloud radars and other payloads. It can obtain meteorological elements and ecosystem information in designated areas in a timely manner, and can observe basic atmospheric information such as surface images, surface temperature, vegetation index, land object types and disaster imaging, wind speed, temperature, and humidity. Due to the lack of communication in the disaster area, it is impossible to obtain meteorological data in the disaster area. By carrying a variety of meteorological payloads on large UAVs, it is possible to first detect surface impacts, land object types, and disaster imaging, and then detect meteorological data such as temperature, humidity, and wind speed in the disaster area according to the observed position, so as to grasp the meteorological data in the disaster area as soon as possible, and use meteorological data in conjunction with health and other departments to avoid the occurrence of other diseases to the greatest extent. Therefore, the UAV meteorological emergency detection system can comprehensively improve the meteorological observation and level of emergency support. Moreover, each load is responsible for detecting different meteorological elements and can work independently. All loads can also work together, which improves the reliability of the entire system and increases the scalability of detecting meteorological elements. The load installation location can be reasonably selected according to the load function, and the loads do not interfere with each other. When all loads work together, they can effectively detect meteorological elements in emergency detection needs.
