【摘要】：本文针对双基地体制下调频中断连续波(FMICW)信号的克拉美罗界问题,利用模糊函数和克拉美罗界之间的关系,给出了目标参数无偏估计的下界。仿真了双基地情况下波形参数对模糊函数形状的影响,以及站址和目标之间的几何构型与目标分辨能力之间的关系。分析表明,双基地雷达目标参数估计克拉美罗界取决于目标到达方向、基线长度以及目标与接收站之间的距离。最后根据克拉美罗界仿真分析了雷达双基地站址选择对目标估计精度的影响。
[Abstract]:In this paper, the lower bound of unbiased estimation of target parameters is given by using the relation between fuzzy function and Clemero bound for the continuous wave (FMICW) signal with frequency modulation interruption under bistatic system. The influence of waveform parameters on the shape of fuzzy function and the relationship between the geometric configuration of the station and the target resolution are simulated. The analysis shows that the estimation of the parameters of bistatic radar targets depends on the direction of arrival of the target, the length of the baseline and the distance between the target and the receiving station. Finally, the effect of radar bistatic site selection on target estimation accuracy is analyzed based on Clemero boundary simulation.
