The invention discloses an airport low-altitude aircraft monitoring method and system, and relates to the technical field of aerospace monitoring, and the method comprises the steps: arranging a plurality of software defined radio receivers in a preset area around an airport; scanning and capturing a radio signal of a low-altitude area, and generating a data packet to be transmitted; transmitting the to-be-transmitted data packet to a central processing server through an edge network, and performing analysis and feature extraction on the to-be-transmitted data packet in the central processing server to generate signal feature information; based on the signal feature information, a multi-source fusion positioning algorithm is adopted, the low-altitude aircraft is positioned, and comprehensive positioning information is generated; in combination with comprehensive positioning information and signal feature information, a dynamic flight behavior model is constructed by using a graph neural network, and potential threats are evaluated in real time. According to the invention, the radio signals in the low-altitude area are accurately captured, processed and classified by using the high-precision software-defined radio receiver and combining the multi-stage wavelet transform noise reduction and the advanced signal classification algorithm.
