The invention discloses a measuring system and method for determining the position of a burst center of a warhead through a wireless sensor network. One or more network units are connected with a relay node through wireless communication, the relay node is connected with a remote monitoring interaction terminal through wireless communication, each network unit comprises an aggregation node and three or more sensor nodes, and information transmission is achieved in a multi-hop transmission mode. The position of the explosion center is calculated through the explosion pressure information according to a node positioning calculation method; the robustness and fault tolerance of the algorithm are considered, errors caused by inaccurate signals can be reduced, and interference of the external environment can be resisted; the sensor nodes only undertake low-complexity tasks of self-positioning and signal acquisition and transmission, so that the energy consumption is reduced, and the life cycle of the whole network
