Background
In the prior art in the field of civil aviation air traffic control, a low-altitude aircraft usually adopts a radar to search a target, then target information is sent to a photoelectric monitoring device to further track, monitor and evidence, and then the target is disposed through an interference device. Through the mode of multi-device cooperative work, the problem that when a single detection source detects a low-altitude small target, the target is shielded instantly to cause untimely treatment is solved to a certain extent, and information complementation is realized.
The following two types of technologies are known for cooperative operation of radar, a photoelectric monitoring device, and an interfering device.
