[0002] In modern radar technology, individual soldier radar equipment has become an important piece of technical equipment due to its portability and efficient target detection capabilities. Especially in complex environments or field operations, lightweight radar can provide soldiers with real-time situational awareness, significantly improving survivability. K-band radar, due to its high-frequency characteristics, has high resolution and a small antenna size, making it very suitable for carrying and use. However, existing K-band individual soldier radars still have many shortcomings in practical applications.

[0003] Currently available man-portable phased array radars generally suffer from large size and heavy weight, making them unsuitable for prolonged carrying and operation by individual soldiers. Furthermore, existing equipment exhibits low modularity and complex internal structures, leading to inconvenient and costly maintenance. Functionally, many radar systems lack efficient signal processing capabilities and flexible beam control mechanisms, limiting their detection accuracy and response speed in dynamic environments. Simultaneously, the high energy consumption and limited endurance of existing radars further reduce their practicality in field environments.

[0004] To address the aforementioned issues, there is an urgent need for a lightweight K-band man-portable phased array radar. This radar should achieve miniaturization, weight reduction, and high efficiency through optimized module design and structural layout. It should possess a simple modular structure for ease of production and maintenance, while innovative design should reduce energy consumption and improve detection performance to meet the practical needs of individual soldier operations and field missions.

[0025] The present invention will be further described in detail below with reference to specific embodiments, but the implementation of the present invention is not limited thereto.

[0026] Figure 1 This is a schematic diagram of the structure of a lightweight K-band man-portable phased array radar provided in an embodiment of this utility model. Figure 1 The layout of the antenna array module 1, signal processing module 2, power management module 3, heat dissipation module 4, and housing 5 is shown. The accompanying reference numerals also include microstrip antenna element 6, battery pack 7, power supply status signal line 8, thermal conductive bonding surface 9, and electromagnetic wave signal transmission line 10. These components together constitute the technical solution of this utility model.

[0027] Firstly, from an overall structural perspective, this portable K-band man-portable phased array radar consists of multiple functional modules, which work together efficiently through close integration. The antenna array module 1 is one of the core components of the radar, its main function being to transmit and receive electromagnetic wave signals. The antenna array module 1 includes multiple microstrip antenna elements 6, which are arranged in a preset array configuration, as detailed in [reference needed]. Figure 1The array in the array enables high-precision target detection. The microstrip antenna element 6 is designed using advanced printed circuit board technology, resulting in a small size, light weight, and high gain performance. In practical implementation, the antenna array module 1 is connected to the signal processing module 2 via the electromagnetic wave signal transmission line 10, thereby completing the signal transmission and processing tasks.

[0028] Signal processing module 2 is the core control unit of the entire radar system. Its main function is to modulate and demodulate the electromagnetic wave signals received by antenna array module 1 and generate corresponding output data as needed. Signal processing module 2 integrates a high-performance digital signal processor and related algorithm modules, enabling it to quickly and accurately analyze and process signals. To meet the needs of different scenarios, signal processing module 2 also has multiple operating modes, including low-power mode and high-performance mode. The switching between these two modes depends on the power supply status signal provided by power management module 3. When power management module 3 is connected to a single battery pack of battery pack 7, signal processing module 2 automatically switches to low-power mode. In this mode, the radar's energy consumption is significantly reduced, thereby extending the device's battery life. When power management module 3 is connected to a dual battery pack of battery pack 7, signal processing module 2 switches to high-performance mode, at which point the radar's detection accuracy and response speed are significantly improved. This automatic adjustment mechanism based on changes in physical power supply status to trigger the operating mode eliminates the need for complex software algorithms, greatly simplifying the operation process and reducing the error rate during use.

[0029] The power management module 3 is an important component of this invention. Its main function is to provide stable power support for the antenna array module 1 and the signal processing module 2, and to monitor the status of the battery pack 7 in real time. The power management module 3 sends a power status signal to the signal processing module 2 via the power supply status signal line 8, which indicates the radar's current operating mode. In practice, the power management module 3 employs efficient power conversion technology to minimize energy loss, and also features overvoltage protection, overcurrent protection, and short-circuit protection to ensure safe operation. Furthermore, the power management module 3 supports hot-swapping, allowing users to replace or add the battery pack 7 as needed, thereby flexibly adjusting the radar's runtime and performance.

[0030] To ensure the stability and reliability of the signal processing module 2 under high-load operating conditions, this invention also includes a heat dissipation module 4. The heat dissipation module 4 is tightly bonded to the signal processing module 2 via a thermally conductive bonding surface 9, effectively reducing the temperature of the signal processing module 2 through heat conduction. The heat dissipation module 4 is made of a high thermal conductivity material and has multiple heat dissipation fins on its surface to increase the heat dissipation area and improve heat dissipation efficiency. In practical applications, the heat dissipation module 4 effectively prevents the signal processing module 2 from experiencing performance degradation or damage due to overheating, thereby improving the reliability and service life of the entire radar system.

[0031] It is worth mentioning that all the aforementioned functional modules are housed within the outer casing 5. Casing 5 not only protects the internal components but also features an optimized design to further reduce the overall weight of the equipment. Casing 5 is made of high-strength, lightweight materials, such as carbon fiber composites or aluminum alloys, ensuring both structural strength and lightweight design. Furthermore, the streamlined shape of casing 5 facilitates carrying and operation by a single soldier, while reducing the impact of wind resistance on equipment performance. The interior of casing 5 also incorporates well-designed wiring channels and securing devices to ensure secure and reliable connections between modules, preventing loosening or damage due to vibration or impact.

[0032] In practical applications, this portable K-band man-portable phased array radar can be widely used in reconnaissance, patrol, and disaster relief. For example, in reconnaissance missions, users can carry the radar equipment and utilize its high-precision detection capabilities to monitor enemy targets in real time. Due to its small size and light weight, it does not cause significant burden during missions, and its long endurance and multiple operating modes can meet the needs of different environments. In patrol missions, the radar can be deployed at key locations for all-weather monitoring. In disaster relief scenarios, the radar can be rapidly deployed to disaster areas to search for survivors or assess the disaster situation, providing crucial technical support for rescue operations.

[0033] During operation, when the antenna array module 1 receives the electromagnetic wave signal reflected from the target, it transmits the signal to the signal processing module 2 via the electromagnetic wave signal transmission line 10. The signal processing module 2 filters, amplifies, and digitizes the received signal, and extracts relevant target information, such as distance, speed, and azimuth, according to a preset algorithm. Subsequently, the signal processing module 2 outputs the processing results to a display terminal or communication device for operators to view or further analyze. During this process, the power management module 3 continuously monitors the status of the battery pack 7 and sends a power status signal to the signal processing module 2 via the power status signal line 8. If a single battery pack is detected, the signal processing module 2 automatically switches to a low-power mode to extend the device's battery life; if dual battery packs are detected, the signal processing module 2 switches to a high-performance mode to improve detection accuracy and response speed. Simultaneously, the heat dissipation module 4 continuously absorbs the heat generated by the signal processing module 2 through the heat conduction bonding surface 9 and dissipates it into the external environment, ensuring that the device maintains good performance even under high-load operating conditions.

[0034] In summary, this invention successfully solves the technical problems of large size, heavy weight, and low modular integration of radar equipment by organically combining the antenna array module, signal processing module, power management module, heat dissipation module, and housing. This invention not only realizes the miniaturization and lightweight design of radar equipment, but also significantly improves the performance and reliability of the equipment through intelligent power supply management and efficient heat dissipation measures, providing strong technical support.
