摘要：

The phased array radar tracking mode occupies most of its resources. In order to solve the problem of contradiction between improving target tracking accuracy and capacity, a beam waveform scheduling strategy considering both the tracking accuracy and radar time resources was proposed. First, the target tracking model is given. Furthermore, the beam scheduling cost-effectiveness ratio and scheduling function are defined. Under the constraints of detection probability and tracking accuracy, the scheduling function values of all current targets are predicted, and schedule target sequence is selected according to the scheduling function values under the constraint of the tracking resource and multi-beam tracking method. Finally, compared with methods of conventional beam waveform scheduling and single-beam scheduling, simulation verifies the effectiveness and superiority of the scheduling function and the multi-beam tracking method under the condition that the number of tracking targets is constant. The scheduling strategy effectively improves the average tracking accuracy and the average sampling interval time of the target, and reduces the loss rate. © 2019, The Editorial Board of Journal of Xidian University.
