Correlation-based multi-sensor collaborative target detection method

The invention discloses a correlation-based multi-sensor collaborative target detection method. The method is characterized by comprising the following steps that sensor nodes measure signals in a monitoring area independently; when the measured value of a certain sensor node exceeds a preset threshold, triggering to generate a dynamic detection cluster; member nodes in the cluster transmit a detection value sequence in a period of time to a cluster head node to form a detection matrix; and the cluster head node calculates the correlation measure among detection vectors in the detection matrix, and judges the existence of a target according to a calculation result. The target detection method provided by the invention is a measured value-based fusion detection method; a single sensor node does not need to perform local judgment; the influence on the judgment result caused by noises can be inhibited effectively; and the detection result has high accuracy. The method can be used in the aspects ...
