Autonomous low-attitude unmanned aerial vehicle defense system based on multi-sensor information fusion

Abstract

The invention relates to the technical field of unmanned aerial vehicles, and discloses an autonomous low-attitude unmanned aerial vehicle defense system based on multi-sensor information fusion. Thedefense system comprises a detection monitoring system used for monitoring a target in a monitoring detection area and uploading the obtained target position and state information to a control computation center; a decision system used for processing related information searched by sensors in the detection monitoring system, obtaining situation information of the target according to a processing result, calculating and obtaining a threat level of the target, and generating a decision command; a disposal system used for executing the corresponding decision command and performing interference oppression on the target; an operation maintenance system used for monitoring the state of each device in real time, completing state data analysis, record and return visit of the devices and monitoringoperation environments and communication links of the devices in real time; and a monitoring center platform used for monitoring and controlling the whole system and disposing the monitored target. According to the scheme, interference defense of the unmanned aerial vehicles can be effectively realized.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an autonomous low-altitude unmanned aerial vehicle defense system based on multi-element sensor information fusion. Background technique [0002] In recent years, with the rapid development of consumer drones and the continuous improvement of national material living standards, the application of low-altitude aircraft such as drones is an emerging industry, and the scale of use is expanding day by day, and the application field is also expanding. However, with the widespread application of low-altitude aircraft such as drones, it has also brought greater security threats to infrastructure, such as dams, bridges, power stations, high-voltage lines, communication towers, airports, high-speed rail facilities, and secrets. The infrastructure will cause immeasurable losses, and the main potential low-altitude safety hazards include: 1) The infrastructure base is regar...

Problems solved by technology

[0005] In the existing technology, the UAV monitoring system, decision-making system, and suppression and disposal system are independent of each other, cannot be linked, and cannot form an organic whole, and each system requires manual operation, which increases labor costs; the system itself cannot be used all-weather, Full-time monitoring requires high skill means for fusion and processing of various observation data; the determination of illegal targets also requires personnel participation, which does not rule out the inherent errors of personnel due to individual differences, which leads to errors in judgment and decision-making, and increases the false alarm rate and false alarm rate; personnel participation is also required in the processing process, which cannot guarantee the correctness of the processing, nor can it effectively evaluate the processing effect
