A Method of Multi-Sensor Data Fusion Based on SPA

Aiming at the problem of multi-sensor data fusion, a method of multi-sensor data fusion based on set pair analysis (SPA) is present in this paper. On the basis of set pair closeness degree, the concept of SPA closeness degree matrix is put forward. Based on the principle of information sharing and merging, The proportion of data provided by every sensor is solved in the process of data fusion. The example in this paper show that this method can solve the question of multi-sensor data fusion preferably.
