为了解决带宽受限的多传感器跟踪系统中机动目标的精确跟踪与带宽的有效利用这一主要矛盾,提出了一种稳健的可变速率机动目标跟踪方法。通过对系统中的非线性部分的分析,明确了目标机动、输入数据速率对跟踪系统模型不确定性的影响,从而得到以目标机动特性为依据动态调节数据采样频率的稳健跟踪方法。仿真试验表明,该方法在稳健跟踪的同时减少了系统通信负担,尤其适用于通信带宽受限的机动目标跟踪系统。
In order to solve the main contradiction between accurate tracking of maneuvering target and effective utilization of bandwidth in multi-sensor tracking system with limited bandwidth, a robust tracking method with variable-rate maneuvering target is proposed. By analyzing the non-linear part of the system, the influence of target maneuver and input data rate on the uncertainty of tracking system model is clarified, and a robust tracking method of dynamically adjusting the data sampling frequency based on the target maneuver characteristics is obtained. The simulation results show that this method can reduce the system communication burden while keeping a steady track, especially for the maneuvering target tracking system with limited communication bandwidth.
