On September 3, 2025, the military parade commemorating the 80th anniversary of the victory of the Chinese People's War of Resistance against Japanese Aggression and the World Anti Fascist War was held in Tiananmen Square in Beijing. This military parade is not only a solemn commemoration of historical victories, but also a concentrated display of the achievements of China's modernization of national defense forces, with the deep integration of sensor technology and national defense becoming a major highlight.
From the equipment reviewed, sensor technology runs through every aspect, demonstrating its crucial role in the modernization of national defense. In the equipment fleet, fourth generation equipment such as new tanks, carrier based aircraft, and fighter jets dominate. These devices are equipped with a large number of advanced sensors, such as high-precision infrared sensors, laser ranging sensors, etc. Infrared sensors can quickly and accurately capture the thermal signals of enemy targets in complex battlefield environments. Even at night or in adverse weather conditions, they enable our equipment to be fully aware of enemy movements, greatly enhancing the initiative and accuracy of combat. Laser ranging sensors provide strong support for precise strikes by weapons, as they can accurately measure the distance of targets, enabling weapons such as shells and missiles to hit targets more accurately, effectively improving the lethality and combat effectiveness of weapons.
The appearance of the unmanned combat group is a vivid manifestation of the integration of sensor technology and national defense. The new type of drone is equipped with various advanced sensors, including high-definition cameras, air pressure sensors, attitude sensors, etc. High definition cameras can transmit real-time battlefield images, providing comprehensive battlefield situational awareness for the command center; Pressure sensors and attitude sensors can ensure that drones maintain a stable attitude during flight and accurately perform various tasks such as reconnaissance, surveillance, and strikes. In addition, anti unmanned equipment in unmanned combat groups also relies on the support of sensors. Through radar sensors and photoelectric sensors, enemy drones can be detected and tracked in a timely manner, providing accurate information for interception and strike.
In the air echelon, advanced early warning command aircraft are the "brain" of the entire air combat system. It is equipped with high-performance radar sensors with powerful detection and information processing capabilities. It is possible to detect enemy aircraft, missiles, and other targets from a distance and transmit this information in real-time to other combat aircraft, achieving efficient coordination and unified command of air combat forces. At the same time, fighter jets, bombers and other aircraft are also equipped with various sensors, such as infrared imaging sensors and radar guidance sensors on air-to-air missiles, which enable our aircraft to have stronger accuracy and lethality in air combat and ground attacks.
In addition to its application in combat equipment, sensor technology also plays an important role in the training and support of military parades. During training, the Beidou positioning system and intelligent evaluation system are utilized to collect real-time information on the position, posture, speed, and other aspects of personnel and equipment through sensors. This enables precise evaluation of training effectiveness, timely detection and correction of problems, and greatly improves the quality and efficiency of training. In terms of equipment support, various intelligent detection terminals can quickly and accurately detect equipment faults and hidden dangers with the help of sensors, providing strong support for timely maintenance and upkeep of equipment, ensuring that the reviewed equipment can be inspected in the best condition.
The military parade on September 3, 2025, has shown us the deep integration of sensor technology and national defense, injecting strong impetus into China's modernization of national defense. With the continuous advancement of technology, sensor technology will play a more important role in future national defense construction, providing a more solid guarantee for China's national security and development.
