System and method for detecting aircraft landing deviating from runway in low-visibility environment

The invention discloses a system and a method for detecting aircraft landing deviating from a runway in a low-visibility environment. The detection system comprises a detection module, a main control module, an alarm module, a relieving module and an imaging module, the method of the detection system comprises the following steps: receiving angle information of a plurality of angle reflectors in real time, and selecting angle information of two echoes returned by one angle reflector; respectively substituting the angle information of the two echoes into a runway deviation detection model to obtain a detection and identification result, and performing two-dimensional imaging on the selected angle information to obtain the relative position of the aircraft and the runway; based on a detection and identification result, selecting to output alarm information or release information; and outputting the relative positions of the airplane and the runway in a visual form. The system monitors and early warns the aircra
