Civil UAVs have the characteristics of low flight altitude, various types of aircraft, complex and changeable flight areas, etc. If there is no reliable cooperative target UAV monitoring platform, UAVs may cause serious security risks to people, property and infrastructure; The main threat of non cooperative target UAVs is that they may cause serious hidden danger to people, property and infrastructure, and pose a serious risk to the control airspace such as key security prevention and control sites, key areas and temporary sites for major activities, which may bring huge economic losses and create a very bad social impact.
"It is very necessary to strengthen the research on UAV supervision technology that integrates low altitude cooperative goals and non cooperative goals of air space integration".
CCTV-7 National Defense and Military Channel reports our UAV reconnaissance, positioning and countermeasure system
The first Individual hand-held UAV detection equipment
UAVs are popular and can be used in many fields, including military and civilian fields. In the recent conflict in Ukraine, both sides sent drones to harass each other. However, the widespread use of UAVs has also brought many potential safety hazards, disturbing people and navigation, posing a serious threat.
One second identification
The drone "does not obey the rules" and has its own sharp weapon to deal with it.
"Attention! There are two UAVs flying 'illegally' in the park without reporting, one of which has a frequency of 2477 MHz and the other has a frequency of 5725 MHz. The UAV anti reaction equipment has automatically locked the target..." In Pujiang Zhigu, Minhang District, a "UAV anti reaction" test is being simulated to pass the independently developed TDOA (time difference of arrival) low altitude monitoring system and products, Detect and identify the "illegal flight" UAV and drive it away accurately.
TDOA UAV detection equipment is deployed in an international airport
For a long time, UAV detection, discovery and identification are technical problems in the radio technology industry. How to judge UAV signal, whether UAV flight is legal and accurately locate flight path are cutting-edge technologies that need to be tackled urgently. TDOA is the English abbreviation of "Time Difference of Arrival". The core technical principle at the bottom is the algorithm of "time difference of signal arrival", which can be used to detect and locate UAVs.
At present, our company has nearly 100 core technology patents, most of which are invention patents. Our company's UAV detection and positioning accuracy has reached the leading position in the industry, and the recognition speed is amazing, which can be completed in one second. If it is determined that the UAV is found, the system will locate and track the UAV. If it is confirmed by comparison that it is a threatening "illegal flight" UAV, the system will automatically start countermeasures to force it to land or return.
The 2019 CCTV Spring Festival Gala is located in Changchun, Jilin Province. Our company joined the UAV defense team at the venue. The TDOA UAV management and control system is deployed to operate 24 hours a day, 24 hours a day, with the central performance stage as the center, 1000 meters from east to west and 700 meters from south to north as the core protection area, covering an area of more than 4 square kilometers.
