MULTIPLE TARGET TRACKING METHOD USING RECEIVED SIGNAL STRENGTHS

摘要

The present invention relates to a multiple target tracking method using a received signal strength indicator (RSSI), and more specifically, to a multiple target tracking method using an RSSI, which generates RSSI data from a plurality of tracking signals detected by a radar, extracts only a tracking signal present within a certain effective distance among tracking signals in which the RSSI data is generated, generates the data related probability of the extracted tracking signal by using the RSSI data, and obtains a state vector computation value and an error covariance value for a target by using a tracking filter to which the data related probability is applied, thus updating the track of the target. According to the present invention, different RSSI data by target is applied to Joint Probability Data-Association (JPDA) or Cheap Joint Probability Data-Association (CJPDA), thus improving the performance of a data related technique.
