Quantum sensor network with multipartite entanglement offers a sensitivity advantage in optical phase estimation over classical scheme. In order to tackle richer sensing problems, we construct a distributed sensor network with four nodes via four partite entanglements, unveil the estimation of the higher order derivative of radio-frequency signal phase, and unlock the potential of quantum target ranging and space positioning. Therefore, taking phased-array radar as an example, we demonstrate the optimal quantum advantages for space positioning and target ranging missions. Without doubt, the demonstration that endows innovative physical conception opens up a widespread application of quantum sensor network.
