Abstract: Because the extraction of feature vector using a single sensor from the target is often incomplete, it is useful to take advantage of irrelevant feature vectors which are extracted by using multisensor for enhancing detection possibility and lowering error possibility. The radar sensor and the infrared sensor are two kinds of the most important sensors in modern military.A method of target identification by information fusion is given to construct feature vectors space. It is proved that the new method of target identification which uses a radar sensor and an infrared sensor is better than the old method of target identification which uses a single radar sensor. The simulation experiments are carried out to show the effectiveness of the new method.
