| 摘 要： | 当目标为宽带信号时,现有单站无源定位方法需要的参数难以获取。而时差和时差变化率是一种宽窄带都适用的观测量。因此,在分析时差和时差变化率所包含目标信息的基础上,建立了一种新的单站对宽带信号源的定位模型,并利用粒子滤波算法对该模型进行滤波处理。仿真实验表明了该方法的有效性。

| Abstract: | It is difficult to obtain the parameters by the existing single observer passive localization methods when the target is wideband signal. A new location model based on motion information of the target contained in the time delay and time delay rate for wideband signal is developed on the basis of fixed single station. Then this model is processed with PF algorithm. Computer simulation verifies the availability of this method. |
