An analysis of tracking gate for maneuvering targets

It is important for a maneuvering target tracking to decide an proper gatesize parameter d in clutter environment. There are 2 problems to set gatesize parameter. One of the problems is that d set for a target in cluttered environment, the other is that d set for a maneuvering target. By the way, assume that a maneuvering target tracking in long-range radar, has been given, the gate radius of range direction and that of cross-range direction are unbalanced. Therefore if the conventional gating is applied to the maneuvering target tracking in long-ranged radar, it is impossible to control the gate radiuses of range direction and cross-range direction in the conventional gating. That is the reason the conventional gating has only one gatesize parameter which influences the gate radiuses of range direction and cross-range direction. To solve this problem, we propose a new gating which can set the gatesize parameter of range direction and that of cross-range direction independently. The computer simulations show an effectiveness of our idea by comparing our method with conventional method.
