Multi Target Tracking by Dynamic Scene Analysis

摘要

An analysis is made per scan of the received returns based on their geometric interrelations only. From this, a large scale view of the tracking and the data received can be taken. Ultimately the ability of the human observer in identifying target formations, specific ECM patterns etc. would be desirable. However, a first step is taken with the objective to make feasible the initiation and tracking of large groups of targets. The analysis algorithm developed has the unique feature of defining a hierarcy of groups. This is the key feature both for its use in identification as well as in the initiation and tracking processes as described below. The method sets no limit on formation size and the track initiation phase is handled with the same ease as tracking as demonstrated in the example. The method is believed to be a goodbasis for multitarget tracking even in a more realistic radar environment and with other kinds of target behavior. The paper presented a radar scene analysis algorithm. It was shown to easily cope with track initiation of a large formation of aircrafts, a problem giving previous methods big problems. The method is believed to be a general multitarget tracking tool but further work must be done to include a more realistic radar environment and other kinds of target behavior.
