The invention relates to an electromagnetic signal monitoring method based on a wireless sensor network. electromagnetic signal monitoring nodes based on the wireless sensor network are arranged in a monitoring area and are used for transmitting monitored electromagnetic signals to convergence nodes through cluster communication and then to information processing central nodes through a multi-hop network, and extraction of integration parameters and state distribution of the electromagnetic signals are completed at the information center. The information center is used for issuing tasks to the electromagnetic signal monitoring nodes through the wireless sensor network and managing the electromagnetic signal monitoring nodes. By adopting the method, the electromagnetic signals in specific areas can be monitored. The invention has the advantages that: the traditional station type signal monitoring instrument is too large to complete outdoor monitoring, while the wireless sensor network is small can be easily arranged; and the wireless sensor network is applied in monitoring of the electromagnetic signals, the monitoring nodes can be arranged closer to the signal source, and the monitoring accuracy can be improved.
