Abstract :
It is important for target tracking to judge targets´ extinction in clutter environment. When a target is in clutter domain, the conventional method of sliding window detection cannot judge target extinction in the clutter domain appropriately, because it considers nothing but target existence probability in gate when a target is in clutter environment. To solve the problem, we propose a new target extinction judgement method which is determined by clutter density, target detection probability and target existence probability in gate. The effectiveness of the proposed method is confirmed through computer simulation
