On April 13-15, 2023, the 10th World Radar Expo was held in Beijing. Zhongan Ruida made an appearance with a full line of low altitude surveillance radars, showcasing products that received great attention from the industry.

        At present, Zhongan Ruida radar products have the advantages of long detection distance (0-50km), large speed measurement range (0-350m/s), high detection accuracy, wide coverage of airspace, high target resolution, support for detection during travel, remote control, and network construction. They can achieve uninterrupted unmanned combat readiness duty all day, all weather, all airspace, and all terrain. Radar can achieve simultaneous detection of air and ground (sea) targets through digital and intelligent software signal processing platforms, and can be quickly upgraded through software reconstruction. It is designed for detecting and warning various types of radars for targets such as traversing aircraft, cruise missiles, bee swarms, hot air balloons, and birds

1，Traverse detection

     Traverse aircraft is a type of unmanned aerial vehicle, with a maximum speed of 230 kilometers per hour and an acceleration time of less than 1 second from 100 kilometers per hour. It has extremely high maneuverability, and criminals use its high-speed and flexible characteristics to attack targets, which poses great harm. The detection and early warning of such targets is a very difficult problem.

      The digital array radar series products developed by Zhongan Ruida achieve continuous and uninterrupted monitoring and early warning of transit aircraft with high search data rates far exceeding traditional phased array radars.

2，Patrol missile detection

        Common types of patrol missiles include the Russian Lancet, the American Spring Knife, and the Israeli Harlop. They can quickly reach the target area and carry out diverse tasks such as patrol flights, reconnaissance and surveillance, damage assessment, and air strikes. They have the characteristics of high cost-effectiveness and intelligence, and have been widely used in recent regional conflicts, from siege operations to air defense suppression, and then to anti tank operations, You can see the figures of different types of cruise missiles, which can almost penetrate existing air defense systems and directly reach the target, bringing great psychological pressure to the opponent. It is another new concept weapon after drones. With the development of electronic technology, cruise missiles can form a "swarm" and launch saturation attacks on the opponent's target.

        With a spear, there must be a shield. The K12T radar series products developed by Zhongan Ruida can achieve remote warning of low altitude and ultra-low altitude rapid patrol missile targets, with a warning distance of over 20 kilometers. The radar can be deployed in a distributed network.

3，Drone swarm detection

        Incorporate drone "swarm" operations into the strategic combat system planning. The         Drone swarm integrates low-cost small drones with multiple mission payloads based on an open system architecture, constructing a combat system with advantages and intelligent features such as durability, low cost, and functional distribution. After any drone within the "swarm" is damaged, the system can still operate in an orderly manner, So it has extremely strong battlefield survival ability and task execution ability, and can complete combat tasks such as saturation suppression, collaborative reconnaissance, and attack. As the main combat unit on the future battlefield, drone swarms have a significant impact on the outcome of the war. Therefore, early warning and disposal of drone swarms are particularly important.

        The K08 radar of Zhongan Ruida can provide early warning for drone swarms with a reflection cross-section of 0.01 square meters invading from 15 kilometers away. The radar has high data rate, high precision, and high resolution, and can accurately detect bee targets and provide accurate guidance for directed energy weapons or electromagnetic interference equipment in real time.

4,Hot air balloon detection

        As a common sounding tool, many countries use hot air balloons for weather forecasting and atmospheric research. Balloons are also often used in the military field. Balloons can carry radar, infrared photoelectric sensors, and are used to detect low altitude and ground targets, such as military bases, military facilities, and key targets in cities. The floating speed of high-altitude reconnaissance balloons is relatively slow. Currently, most fighter radar The radar of large-scale air defense systems has failed to effectively detect and monitor such targets, and the problem of mid to high altitude balloon detection has attracted attention from countries around the world.

        The Zhongan Ruida K12 radar can achieve stable tracking of high altitude, slow speed, and stationary floating balloons. The tracked floating object information is reported to the command center, making it easy for the command center to grasp the dynamics of the floating object in real time and make corresponding decisions. It plays a role in filling the blind spots of large air defense system radars.

5,Bird detection and identification

        Within the clearance protection zone of military and civilian airports, birds pose a great threat to the takeoff and landing of aircraft. Bird strikes are most common at low altitudes ranging from 100 to 3000 meters. This means that airports must deploy necessary bird detection, management, and control equipment to prevent bird strikes. Bird detection radar, as the most effective and reliable detection sensor, provides precise support for airport bird control equipment.

        The Zhongan Ruida bird detection radar can balance bird and drone targets. For DJY Class 3 drones or single pigeons weighing over 300 grams, the detection distance is not less than 10 kilometers, and for bird flocks, the detection distance is not less than 20 kilometers. A single radar can detect targets with a capacity of over 1000 batches, meeting different detection needs.

        Radar has the ability to recognize targets based on multi-dimensional features. It can recognize and classify targets such as drones and birds based on the speed, height, RCS size, and micro motion characteristics of the target. Combined with the high-resolution ability of radar, it provides information on the number and size of bird groups, providing accurate information for bird situation analysis.

6,Integrated air and ground detection

        It is precisely through years of continuous research and development investment and technological accumulation that Zhongan Ruida has the ability to solve the global problems in the field of "low slow small" target detection. Based on years of product technology accumulation and profound insights in the field of low altitude safety, it is possible to continuously develop new practical products. For example, the multi-functional radar based on two-dimensional phased array system launched at this expo has achieved air, ground Simultaneously monitoring water surface intrusion targets, with the function of searching and tracking at the same time, reducing the deployment of detection sensors.

        The magic is one foot high, the road is one foot high. Zhongan Ruida is determined to move forward and continues to provide users with reliable and practical low altitude surveillance radar products and mature solutions.
