  • To solve the problem of sensor systematic bias estimation in sensor network, a systematic bias fusion estimation algorithm was presented based on multi-sensor multi-target information. To solve the forenamed problem, the algorithm was constituted a two layer fusion structure. In order to improve the precision of corresponding combination estimation, the first layer fuses the multi-sensor combination state estimation information with feedback, so the estimation precision of systematic bias can also be improved. While, the second layer fuses the multi-target systematic bias estimation information in order to further improve the estimation precision. The monte-carlo simulation result shows that the algorithm can make sufficient use of the multi-sensor multi-target information with fusion structure, and achieve an exact and real-time estimation of the multi-sensor systematic bias.
