According to the method, on the basis of clustering of the wireless sensor network, blind detection is carried out on the intra-cluster signals after benchmark sensor nodes are scrambled through an ant colony optimization algorithm, sending signals of the benchmark sensor nodes are restored, and corresponding channels are estimated; then by the utilization of the correlation between the intra-cluster sensor nodes, transmission channels of other sensor nodes are obtained, and the sending signals of non-benchmark sensor nodes are restored through the estimated channels and a descrambler. The blind detection method can easily, conveniently and effectively achieve blind detection on the intra-cluster signals of the precision agriculture wireless sensor network.
