摘要
D-S证据理论在目标识别中有着广泛的应用,是较好的数据融合方法之一,但在证据高度冲突时,会产生有悖常理的结果。针对此问题,引入传感器的可信度,提出了一种新的改进算法。该算法弥补了D-S证据理论所存在的不足,比其他改进算法融合效果好,此算法应用于水下目标识别,计算结果表明提高了水下目标识别的准确性和有效性。
D-S evidence theory is widely used in target recognition. It is an effective method of multi-sensor data fusion. However,it involves counter-intuitive behaviors when the high conflict information exists. In view of the problem,the reliability of sensor is introduced and the new algorithm is proposed. The algorithm makes up for the shortcomings of D-S evidence theory,and has better fusion effect than other improved algorithms. The algorithm is applied in submarine target recognition and the calculation result indicates that the algorithm is effective and correct.
