A wireless sensor network architecture based on multifunctional and compound sensors comprises several sensing modules including a plurality of first sensor nodes and a second sensor node. The first sensor nodes are used for collecting a target signal after sensing that a moving target enters a detection area, extracting feature information of the moving target, analyzing the feature information of the moving target to form primary target information, and transmitting the primary target information to the second sensor node, The second sensor node performs moving target matching and association on the primary target information of the moving target that is transmitted by the plurality of first sensor nodes, collects the associated primary target information to form secondary target information. A control module used for synthesizing and calibrating the secondary target information, and obtaining by merging the calibrated secondary target information, the situation evaluation of the moving target to form advanced target information.
