【摘要】:本文針對雙基地體制下調頻中斷連續(xù)波(FMICW)信號的克拉美羅界問題,利用模糊函數(shù)和克拉美羅界之間的關系,給出了目標參數(shù)無偏估計的下界。仿真了雙基地情況下波形參數(shù)對模糊函數(shù)形狀的影響,以及站址和目標之間的幾何構型與目標分辨能力之間的關系。分析表明,雙基地雷達目標參數(shù)估計克拉美羅界取決于目標到達方向、基線長度以及目標與接收站之間的距離。最后根據克拉美羅界仿真分析了雷達雙基地站址選擇對目標估計精度的影響。
[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.
