Embodiment Construction
[0118] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0119] The extended target tracking method in which the multi-sensor existence monitoring area partially overlaps in the present invention is specifically implemented according to the following steps:
[0120] Step 1. In the tracking problem based on the extended goal, in general, a random set is used To represent the state of the expanded target at time k, the information included in the state of the expanded target at time k is: the position, velocity and acceleration of the target's center of mass;
[0121] in random set middle, Indicates the state of the i-th extended target at time k, N x,k Indicates the number of targets at time k;
[0122] Preset the i-th extended target state vector as Its dynamic equation is as follows:
[0123] x k + 1 ...
