A haze weather monitoring method using satellite signal of EBPSK modulation is constructed in this paper. The core of the method is a three-dimensional (3D) water vapor reconstruction model. The distances between satellites and ground-based receivers are known. In the calculation process, troposphere delay could be solved by differential process. The troposphere delay is used for water vapor distribution calculation on the signal path. Raw water vapor data is received through the array of land-based receiver. The boundary values are presumed known, the 3D distribution in of water vapor is calculated by the 3D haze weather monitoring model. In order to improve the accuracy of the calculation, the differential method and average method are used as error reduction strategies. The validity of 3D water vapor reconstruction model is proved by the calculation example of land-based EBPSK satellite array receivers.
