Continuous and stable tracking of the ground maneu-vering target is a chal enging problem due to the complex terrain and high clutter. A col aborative tracking method of the multi-sensor network is presented for the ground maneuvering target in the presence of the detection blind zone (DBZ). First, the sen-sor scheduling process is modeled within the partial y observable Markov decision process (POMDP) framework. To evaluate the target tracking accuracy of the sensor, the Fisher information is applied to constructing the reward function. The key of the proposed scheduling method is forecasting and early decision-making. Thus, an approximate method based on unscented sam-pling is presented to estimate the target state and the multi-step scheduling reward over the prediction time horizon. Moreover, the problem is converted into a nonlinear optimization problem, and a fast search algorithm is given to solve the sensor scheduling scheme quickly. Simulation results demonstrate the proposed non-myopic scheduling method (Non-MSM) has a better target tracking accuracy compared with traditional methods.
