【摘要】 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。更多还原

【Abstract】 A robust variable-rate target tracking method was developed as a tradeoff between tracking accuracy and data transmission rate in bandwidth-constrained multiple-sensor tracking systems.The analysis of nonlinear-part in tracking systems was carried out,which indicated the impact of the maneuver and the input data rate on the system model uncertainty.Robust tracking is achieved by adjusting the input data rate according to the target motion characteristics.Simulations show that the algorithm gives robust tracking of sharp turns and reduces of communications during slow maneuvers,which is suitably applied to bandwidth-constrained tracking systems.更多还原
