Embodiment

[0050] After the system is started, perform initialization settings, complete the establishment of the spatial coordinate system, and check whether each component is working normally. After initialization, the directional receiving antenna starts to cruise and enters the next step.

[0051] During the cruising process, the directional receiving antenna finds the signal of the intruding UAV, and the multi-antenna co-processor is activated to calculate the spatial coordinates of the UAV according to the distribution of the intruding UAV signal in space.

[0052] The central display console obtains the spatial coordinates of the intruding UAV, and the alarm unit sends out an alarm. The central controller judges the interference sub-interval to which the intruding UAV belongs, and selects the distributed infrared jammer that needs to be turned on according to the set mode.

[0053] It is necessary to turn on the infrared jammer control unit to obtain the space coordinates of the U...

Abstract

The invention discloses a distributed unmanned aerial vehicle infrared jamming system based on directional receiving antennae. The system comprises the directional receiving antennae, a multi-antennacoprocessor, a central display controller, an energy communication module and distributed infrared jammers. According to the system, a distributed infrared jamming scheme is adopted, and by placing the infrared jammers in protection areas in a distributed mode, the problems that due to the fact that a single jammer is adopted in the current civil unmanned aerial vehicle infrared jamming field, thejamming efficiency is low, the needed power consumption is high, and the jamming effect is not ideal are solved; and meanwhile the directional receiving antennae are adopted, and by analyzing the spatial signal distribution of unmanned aerial vehicle signals, the coordinates of an unmanned aerial vehicle are obtained to implement jamming.

Description

technical field [0001] The invention relates to the technical field of UAV interception, in particular to a method and related devices for UAV infrared interference, in particular to a method for UAV infrared interference using a distributed UAV infrared interference system based on a directional receiving antenna. Background technique [0002] In recent years, with the continuous development and maturity of technologies in the fields of information, control, and communication, UAVs have the advantages of low cost, small size, light weight, easy manipulation, good flexibility, strong adaptability, and high stability. The overall rapid development of the drone industry has gradually lowered the threshold for the use of consumer and industrial drones, and has been widely used in both civilian and military fields. According to statistics, in 2015, the global sales of drones was about 587,000, of which military drones accounted for about 3%, and civilian drones accounted for 97%...
