Easily Detecting High-Altitude Balloons Similar to F35

Recently, according to the Hong Kong “South China Morning Post,” Chinese scientists have made significant breakthroughs in conventional weather radar technology. According to the latest officially released information, they have successfully developed a new technology that can use existing weather radars to detect small high-altitude balloons with a radar cross-section comparable to that of the F-35 stealth fighter jet. These balloons, due to their small size and low speed, were previously difficult to capture by traditional radar systems.

The core of this technology lies in software innovation and upgrades, rather than expensive hardware modifications. This is particularly important because it means that we can significantly enhance the functionality and efficiency of weather radars through software updates without the need to replace existing equipment. What is even more exciting is that the cost of this upgrade is very low, providing an economical and efficient solution for China in the fields of aviation monitoring and national defense security.

With this technology, weather radars can not only continue to perform weather forecasting but also take on the task of monitoring small airborne objects. This is undoubtedly a significant technological advancement for enhancing our national security protection network. In today’s increasingly intense global technological competition, this achievement by Chinese scientists showcases our strength and wisdom in the field of technological innovation.

Innovative Solutions by Chinese Scientists for Detecting “Stealth” Aircraft

According to recently released official information, China has made remarkable progress in detecting low radar signal signature aircraft (commonly known as “stealth”). The information revealed that Chinese defense scientists conducted an unprecedented “high-altitude balloon detection technology” field test in Neijiang, Sichuan. The radar cross-section of the balloon used in the test was only 16 square centimeters, equivalent to the radar cross-section of an F-35 stealth fighter.

In a paper published in the “Journal of Aeronautics,” the radar technology research team from the National University of Defense Technology of the Chinese People’s Liberation Army pointed out that ordinary weather radars can effectively detect these low-speed, low radar cross-section targets.

In complex terrains and electromagnetic interference environments, traditional radar detection methods find it challenging to distinguish them from background noise. The unique algorithm developed by Chinese scientists can accurately detect the electric field spatial disturbances caused by balloons and identify and locate them based on other physical parameters.

The challenge of this technology lies in extracting the signal of the balloon from background noise such as ground clutter and radio frequency interference. The researchers provided detailed noise elimination methods and measures to reduce false alarm rates in their paper.

Notably, this technology does not require changing the radar’s operating mode, making it simple and convenient to implement, without the need to accumulate multiple frames of data or continuously track the target.

This breakthrough by Chinese scientists is not only technologically advanced but also economically practical. They only used common weather radars without any hardware modifications, merely upgrading the signal processing software. This adds new functionality to the radars originally used for weather forecasting, enabling them to detect various types of balloons without additional hardware costs.

This technology provides a new application method for the widely used high-performance weather radars globally. Compared to expensive military radar systems, using weather radars to track balloons is more economical and efficient.

This breakthrough by Chinese scientists not only demonstrates China’s strength in the field of technology but also reflects our wisdom and innovation in problem-solving. Furthermore, the successful application of this technology will greatly enhance our national air defense security, providing more protection for public safety.

This is not only a victory for technology but also a choice of wisdom. In this rapidly developing era of information and globalization, those who can master the technological high ground can better protect the security of the country and the interests of the people.

Strategic Significance: Technological Innovation and National Defense Security

In the current international situation, the importance of aerial surveillance and defense systems is increasingly prominent. Traditional air defense radars perform well in detecting large aircraft, but their performance is often limited when dealing with low-speed, small targets.

The balloon detection technology developed by Chinese scientists not only solves this problem but also improves the overall response capability of the defense system, significantly enhancing the country’s air defense power.

By simply upgrading the software, ordinary weather radars are endowed with military detection capabilities. This innovation not only saves a lot of defense expenditure but also makes it possible for every corner’s weather radar station to become an outpost of national defense.
