英文摘要：

To resolve the contradiction of accuracy and efficiency in target detection in multi-sensor system, this paper pro- posed a target detection algorithm with collaborative decision making function and a design scheme of sensors. First, this algo- rithm offered the 3 dimension definition according to the time, space and frequency in multi-sensor system and analyzed the space and time characteristics. Second, it analyzed the variation rules of hard and soft decision making in target detection in terms of binary test and target optimization detection and built a decision making mechanism of target detection based on col- laboration. Finally, it proposed a design scheme of sensor head structure and target detection of hard and soft collaboration de- cision making based on dynamic space and time characteristics. The experiment results show that the new scheme of target de- tection has obvious advantage in detection accuracy and efficiency as well as coverage and utilization rate of resource.
