[0008] The technical principle of the above scheme is as follows: the signal processor first generates control instructions of the radar transmitting signal according to preset monitoring parameters and algorithms, the instructions are transmitted to the transmitter through the output end of the signal processor, the transmitter converts the instructions into radio frequency signals suitable for transmission of the transmitting antenna after receiving the instructions, and then transmits the radio frequency signals to the transmitting antenna, the transmitting antenna transmits the radio frequency signals in the form of electromagnetic waves to the air for detecting thunderstorm clouds; the receiving antenna receives the radar echo signals reflected from the thunderstorm clouds, the anti-interference component can identify and filter out the interference signals in the environment, the received radar echo signals are transmitted to the receiver through the receiving antenna, the receiver processes the signals and then converts them into digital signals transmitted to the signal processor, the signal processor analyzes and processes the received radar echo signals, analyzes characteristic parameters such as intensity, frequency and phase of the radar echo signals, the signal processor can identify key information such as position, shape and intensity of the thunderstorm clouds, according to the information, the signal processor can further judge the development trend and potential threat of the thunderstorm clouds, so as to generate early warning information.
[0009] The above scheme has the following beneficial effects:
[0010] 1、In the radar monitoring process, the anti-interference component arranged on the receiving antenna can intelligently identify and effectively filter out various interference signals in the environment, such as electromagnetic noise and clutter, so that the received radar echo signals remain pure and accurate, avoiding false positives or false negatives caused by interference signals, improving the stability and reliability of the device, and ensuring the accuracy and reliability of the monitoring data, so that the device can maintain excellent performance in complex weather environment, providing a powerful guarantee for real-time monitoring and early warning of thunderstorm clouds.
[0011] 2、The shielding layer is arranged on the side walls of the transmitting box and the receiving box, which plays an effective electromagnetic shielding role. This design can significantly reduce the influence of external electromagnetic interference on the radar device, ensure that the radar signal is not disturbed by external electromagnetic waves during transmission, and significantly improve the quality of the received radar echo signal. High-quality signals mean more accurate extraction of thunderstorm cloud information, which improves the accuracy of monitoring and early warning. In addition, the shielding layer not only reduces external electromagnetic interference, but also protects internal electronic components.

[0013] Further, the shielding layers are all corrugated structures.
[0014] Beneficial effects: The corrugated structure design makes the shielding layer maintain lightness while having higher strength and rigidity. By increasing the surface area and complexity of the shielding layer, more electromagnetic waves are effectively blocked and absorbed, significantly enhancing electromagnetic shielding effectiveness. At the same time, the corrugated shielding layer can provide better electromagnetic isolation effect than the traditional flat shielding layer, reducing the influence of external electromagnetic interference on the internal electronic components of the radar device. In addition, the corrugated structure also improves the anti-deformation and anti-impact ability of the box. In severe weather conditions such as thunderstorms and strong winds, this structure can better resist external environmental pressure and impact, maintain the integrity and stability of the shielding layer.
[0015] Further, the shielding layers are all made of white copper metal material.
[0016] Beneficial effects: As a metal material with excellent electrical conductivity and magnetic permeability, the high electrical conductivity of the silver-white copper enables the shielding layer made of silver-white copper to efficiently absorb and reflect electromagnetic waves, effectively blocking external electromagnetic interference from entering the radar device interior while also absorbing internal escaping electromagnetic waves, thereby ensuring the purity and accuracy of radar signal transmission and reception. Meanwhile, its good magnetic permeability also helps guide and dissipate potential electromagnetic interference, further enhancing the effectiveness of electromagnetic shielding.
[0017] Further, the anti-interference assembly includes an attenuator fixedly connected to the antenna element of the receiving antenna, and an input end of the attenuator is connected with the receiving antenna signal.
[0018] Beneficial effects: The presence of the attenuator enhances the dynamic range of the radar device. Dynamic range refers to the ratio of the maximum and minimum signal strengths that the device can handle. In the received radar signal of the receiving antenna, there are both strong signals and weak signals. Through precise regulation of the attenuator, the device can better adapt to signal inputs of different intensities, expanding the range of signals that the device can handle and improving the flexibility and adaptability of the device.
[0019] Further, the transmitter is installed on the antenna element of the transmitting antenna.
[0020] Beneficial effects: The transmitter is designed to be directly installed on the radar antenna element, which significantly reduces the length of the waveguide and transmission loss, while eliminating the rotating joint, optimizing the performance and reliability of the system, greatly reducing the loss in the transmission of radio frequency signals, improving the transmission efficiency, ensuring that the transmitter operates efficiently and stably in a small volume, and providing stable high-power signals, suitable for high-precision and long-range detection radars.
[0021] Further, the receiver is a digital receiver with a sampling rate of 200MSPS, and an input end of the digital receiver is connected with the signal output end of the attenuator.
[0022] Beneficial effects: The digital receiver uses a sampling rate of up to 200MSPS, which can capture and record received signals with extremely high precision. Combined with the use of the attenuator, the digital receiver can process precisely regulated signals, further improving the accuracy of signal processing. The high sampling rate ensures that details and minor changes in the signal are preserved, providing a rich information base for subsequent signal analysis and processing. In addition, the sampling rate of 200MSPS enables the digital receiver to process signals within a wider frequency range, thereby enhancing the dynamic performance of the device.

[0024] Beneficial effects: By reasonably arranging the air outlets, air inlets and ventilation holes on the antenna platform, uniform airflow distribution in the processing box is realized, which helps to reduce the heat island effect, i.e. the phenomenon of local area temperature being too high to cause system performance degradation, and uniform airflow distribution ensures that the signal processor can be fully cooled, thereby improving the overall heat dissipation effect of the device.
[0025] Further, the transmitting box and the receiving box are both provided with openings at the top, and the openings are all inclined slope structures with the side close to the other one as the slope top and the side far from the other one as the slope bottom.

[0040] The specific embodiments will be described in further detail below:
[0041] Embodiment 1:
[0042] As shown in the accompanying drawings Figure 1 、 Figure 2 、 Figure 3 and Figure 4 : a thunderstorm cloud monitoring and early warning device based on radar, comprising a fixed seat 1 for bearing support, the top end of the fixed seat 1 is fixedly connected with an antenna platform 2, characterized in that the antenna platform 2 is fixedly connected with a transmitting box 3, a processing box 4 and a receiving box 5 from left to right in sequence, a transmitting antenna 8 is fixedly connected in the transmitting box 3 through bolts, a receiving antenna 10 is fixedly connected in the receiving box 5 through bolts, by setting the transmitting box 3 and the receiving box 5 to separate the operation of transmission and reception, and respectively setting the transmitting antenna 8 and the receiving antenna 10, a double-antenna structure of transceiver separation is realized, the frequency of the received signal and the transmitted signal is reduced to affect each other, which is conducive to maintaining high-performance signal transmission.
[0043] A signal processor 6 for controlling radar transmission and receiving radar processing is fixedly connected in the processing box 4, the model of the signal processor 6 is preferably a TMS320 series DSP main control board, a shielding layer 7 is fixedly connected on the side wall of the transmitting box 3 and the receiving box 5, the design of the shielding layer 7 increases the isolation degree between the transmission and reception channels, improves the independence of the transmission and reception, effectively shields the influence of external electromagnetic waves on the internal circuit, at the same time prevents the electromagnetic waves generated inside from radiating outward, and ensures the normal work of the transmission and reception circuit and the stable transmission of the signal.
[0044] A transmitter 9 is connected to the input end of the transmitting antenna 8, a receiver 11 is fixedly connected in the processing box 4 through bolts, the input end of the transmitter 9 is connected with the output end of the signal processor 6, an anti-interference component for receiving anti-interference is arranged on the receiving antenna 10, the anti-interference component comprises an attenuator 12 on the antenna oscillator which is integrally formed with the receiving antenna 10, the model of the attenuator 12 is preferably a SHK series attenuator 12, the input end of the attenuator 12 is connected with the receiving antenna 10, the output end of the attenuator 12 is connected with the input end of the receiver 11, and the output end of the receiver 11 is connected with the input end of the signal processor 6.
[0045] The specific implementation process is as follows: in the monitoring process of thunderstorm cloud, first, the transmitter 9 receives the instruction signal from the signal processor 6, these instruction signals are transmitted to the transmitting antenna 8 after being encoded and modulated, and the transmitting antenna 8 radiates these high-frequency electromagnetic wave signals into the atmosphere, and these signals will be reflected, scattered and other phenomena when encountering weather targets such as thunderstorm clouds in the propagation process.
[0046] The reflected signal, i.e. echo signal, will be captured by the receiving antenna 10. In the design of the receiving antenna 10, anti-interference components are particularly added, among which the attenuator 12 plays a key role. The attenuator 12 can effectively reduce the intensity of strong interference signals received by the receiving antenna 10, such as electromagnetic interference from other electronic devices or noise from the natural environment, while maintaining the sensitivity to weak signals reflected by thunderstorm clouds. This not only improves the signal-to-noise ratio of the signal, but also enhances the anti-interference ability of the device, making the monitoring results more accurate and reliable.
[0047] After being processed by the attenuator 12, the received echo signal is sent to the receiver 11 for amplification, demodulation, and other processing to restore the original radar signal data. These data are then transmitted to the signal processor 6 for further analysis and processing. The signal processor 6 uses advanced algorithms and techniques to filter, denoise, and extract features from the received signal, thereby identifying key information such as the location, intensity, and movement speed of thunderstorm clouds.
[0048] By setting the transmitting box 3 and the receiving box 5 to separate the transmission and reception operations, and by setting the transmitting antenna 8 and the receiving antenna 10 respectively, the device realizes a dual-antenna structure with separate transmission and reception. This significantly reduces the mutual influence of the frequency of the received signal and the transmitted signal, maintains high-performance signal transmission and reception, and further improves the isolation between the transmission and reception channels through the design of the shielding layer 7. This effectively shields the influence of external electromagnetic waves on the internal circuit, prevents the external radiation of internally generated electromagnetic waves, and ensures the normal operation of the transmission and reception circuits and the stable transmission of signals.
[0049] This radar-based thunderstorm cloud monitoring and warning device, through its unique dual-antenna structure with separate transmission and reception and anti-interference design, not only improves the accuracy and reliability of thunderstorm cloud monitoring, but also enhances the stability and anti-interference ability of the device. This is of great significance for timely warning of thunderstorm weather and ensuring the safety of people's lives and property. In addition, the device is easy to operate and maintain, and is suitable for various weather monitoring and warning scenarios.
[0050] Example 2:
[0051] As shown in the accompanying drawings Figure 2As shown, different from example 1, the shielding layers 7 are all corrugated structures, the design of the corrugated structure increases the surface area and thickness of the shielding layer 7, in addition, the corrugated structure can also enhance the mechanical strength and stability of the shielding layer 7, thereby improving its shielding effect on electromagnetic waves and shielding effect in complex environment. And the shielding layer 7 is made of white copper metal material, white copper (copper nickel zinc alloy) has excellent shielding effect, good corrosion resistance and welding performance, its toughness, high strength, rich elasticity, easy to process into various shapes, corrugated white copper shielding layer 7 can more effectively block and weaken the propagation of electromagnetic waves, reduce the interference of external electromagnetic waves on internal circuit or device, especially suitable for thunderstorm cloud monitoring and early warning device, because thunderstorm weather can produce strong electromagnetic wave interference, and the corrugated white copper shielding layer 7 can effectively protect the internal circuit from interference.
[0052] The specific implementation process is as follows: when transmitting electromagnetic wave signals and receiving echo signals, electromagnetic waves will reflect, absorb and scatter when encountering the shielding layer 7, thereby reducing the interference of electromagnetic waves on internal circuit or device.
[0053] Example 3:
[0054] As shown in the accompanying Figure 3 As shown, different from example 2, the transmitter 9 is installed on the antenna oscillator of the transmitting antenna 8, this design scheme installs the transmitter 9 on the antenna arm, which greatly reduces the loss in the transmission of radio frequency signals and improves the transmission efficiency. The design ensures that the transmitter 9 operates efficiently and stably in a small volume, the transmitter 9 includes a metal shielding box 901 integrated with the antenna oscillator of the transmitting antenna 8, the integrated design reduces the loss of signals in the transmission process and improves the efficiency and accuracy of signal transmission. In addition, the metal shielding box 901 not only protects the electronic components inside the transmitter 9 from external electromagnetic waves, but also prevents the electromagnetic waves generated by the transmitter 9 from leaking outward, thereby enhancing the anti-interference ability of the entire device and protecting the electronic components inside the transmitter 9 from the influence of external electromagnetic waves. The inner wall of the metal shielding box 901 is fixedly connected with a transmitting PCB mainboard for processing transmitting signals away from the transmitting antenna 8.
[0055] The specific implementation process is as follows: the transmitting PCB mainboard amplifies and modulates the instruction signals from the signal processor 6 and then transmits them to the transmitting antenna 8 for radiation. During this process, irregular electromagnetic waves are effectively blocked and reflected by the metal shielding box 901, and external electromagnetic wave signals are also blocked and reflected, thereby protecting the electronic components inside the transmitter 9 from external electromagnetic waves and reducing the influence of internal electromagnetic waves on external signal transmission.
[0056] Example 4:
[0057] The difference between the embodiment 3 is that the receiver 11 is a digital receiver 11 with a 200MSPS sampling rate. The combination of high sampling rate and digital signal processing technology enables the digital receiver 11 to capture more fine and accurate thunderstorm cloud reflection signals, which helps to reduce signal distortion and noise interference, and improves the reliability and accuracy of the signals.
[0058] The specific implementation process is as follows: when the electromagnetic wave signals reflected by the thunderstorm cloud are captured by the receiving antenna 10, the signals are first processed by the attenuator 12, and then sent to the input end of the digital receiver 11. The digital receiver 11 is equipped with a high-performance analog-to-digital converter (ADC) inside, which samples the received signals at a sampling rate of 200MSPS, meaning that in each second, the ADC will collect 2 million signal samples, thereby ensuring the integrity and time resolution of the signals. High-speed sampling is the key to capturing rapidly changing thunderstorm cloud reflection signals, which enables the digital receiver 11 to capture subtle changes and characteristics of the signals.
[0059] Embodiment 5:
[0060] As shown in the accompanying Figure 2 The difference between the embodiment 4 is that the processing box 4 is provided with a plurality of air outlets 13 on the top wall, and a heat dissipation fan 15 is fixedly connected inside the processing box 4 above the signal processor 6. The bottom wall of the processing box 4 is provided with a plurality of air inlets 14, and the antenna platform 2 is also provided with a plurality of ventilation holes corresponding to the positions of the air inlets 14. Through the design of air flow and the installation of the heat dissipation fan 15, the heat generated by the signal processor 6 can be quickly taken away, ensuring that its working temperature always remains within a safe range, which helps to improve the stability and service life of the signal processor 6.
[0061] The specific implementation process is as follows: when the signal processor 6 starts to work, the internal electronic elements will generate heat, causing the temperature to rise. At this time, the heat dissipation fan 15 is activated and starts to rotate at a certain speed. The rotation of the fan produces a downward air flow, which extracts the hot air inside the processing box 4 from the air outlets 13 on the top wall, accelerates the transfer and diffusion of heat, and effectively reduces the temperature of the signal processor 6 and its surrounding environment. At the same time, the plurality of air inlets 14 on the bottom wall of the processing box 4 allow external cold air to enter the processing box 4, and the cold air forms an upward air flow inside the box, which forms a convection with the downward air flow generated by the heat dissipation fan 15, further promoting the exchange and emission of heat.
[0062] Embodiment 6:
[0063] As shown in the accompanying Figure 2As shown, different from example 5, both the transmitting box 3 and the receiving box 5 are provided with an opening 16 at the top, and the opening 16 is in a slope shape structure with the top side of the opening 16 being the slope top and the bottom side of the opening 16 being the slope bottom.
[0064] The specific implementation process is as follows: when the signal is emitted from the transmitting box 3, it will gradually spread along the slope-shaped opening 16 and form a more concentrated signal beam at the receiving box 5, thereby improving the sensitivity and accuracy of the receiving. In addition, the slope-shaped structure reduces the reflection and scattering of the signal at the edge of the box, thereby improving the transmission efficiency and directivity of the signal. The design of the slope-shaped opening 16 also takes into account the ventilation and heat dissipation requirements of the box. During the transmitting and receiving process, the electronic components inside the box will generate a certain amount of heat. The slope-shaped opening 16 can guide the external air to flow naturally into the box, forming a convection, thereby helping to dissipate heat.
[0065] Example 7:
[0066] Different from example 6, the output end of the signal processor 6 is also signal-connected with a display screen, and the display screen is preferably a RadarVision Pro-X9000 display. The display screen is installed at a position convenient for the user to view. The processed signal data is presented to the user in an intuitive and visual manner through the display screen, thereby greatly improving the readability and understanding of the information.
[0067] The specific implementation process is as follows: after the signal processor 6 completes the collection, processing and analysis of the input signal, a series of processing results or data will be generated. These data are transmitted to the display screen in the form of electrical signals or digital signals through the output end of the signal processor 6. After further processing and conversion inside the display screen, the received signal data are organized into forms such as graphics, images or text that can be recognized by the user, thereby realizing the early warning effect of thunderstorm cloud monitoring.
[0068] Obviously, the above examples are only examples for the sake of clarity, and do not limit the implementation. For those skilled in the art, other different forms of changes or variations can be made on the basis of the above description. Here, it is not necessary and impossible to exhaust all the implementation. The obvious changes or variations derived therefrom are still within the protection scope of the present application.
