The invention is a cooperative spectrum detection method based on backscattering and air calculation. This method considers that in the 5G cellular Internet of Things scenario, widely distributed mobile user equipments act as spectrum detection assistants, and work together to help requesters obtain the current spectrum status. The specific steps are as follows: each detection user first uses backscatter to directly backscatter the received spectrum signal with the requester as the target, without the need for local perception and data processing procedures. Then, using air computing, all the spectrum signals reflected by the detection assistant are reported to the requester through the same backscatter channel, and the superposition of the backscatter spectrum signals is realized by using the accumulation characteristics of the wireless channel. Finally, the requester samples and analyzes the received air-fused spectrum signal to make a final spectrum detection decision.
