【摘要】：本文針對(duì)雙基地體制下調(diào)頻中斷連續(xù)波(FMICW)信號(hào)的克拉美羅界問(wèn)題,利用模糊函數(shù)和克拉美羅界之間的關(guān)系,給出了目標(biāo)參數(shù)無(wú)偏估計(jì)的下界。仿真了雙基地情況下波形參數(shù)對(duì)模糊函數(shù)形狀的影響,以及站址和目標(biāo)之間的幾何構(gòu)型與目標(biāo)分辨能力之間的關(guān)系。分析表明,雙基地雷達(dá)目標(biāo)參數(shù)估計(jì)克拉美羅界取決于目標(biāo)到達(dá)方向、基線長(zhǎng)度以及目標(biāo)與接收站之間的距離。最后根據(jù)克拉美羅界仿真分析了雷達(dá)雙基地站址選擇對(duì)目標(biāo)估計(jì)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.
