| 摘 要： | 针对测角频差无源定位问题,提出了一种快速有效的解析定位方法,该方法通过引入中间量,将辐射源位置非线性估计问题转化成两个加权线性最小二乘估计问题,简化了定位解算.该方法无需进行参量搜索,比搜索法运算量小;无需初始值引导,比高斯-牛顿迭代法使用方便.在结构上,建立了观测模型,然后给出了辐射源定位误差对应的克拉美罗限,阐述了...

| Abstract: | For hybrid direction of arrival(DOA) and frequency difference of arrival(FDOA) passive localization,a fast and effective algebraic solution is proposed.This method converts the emitter position nonlinear estimation problem into two weighted linear least-squares minimization,which simplifies the emitter localization process.The proposed means does not have the search procedure,so it has less computational load than traditional search method.Furthermore,it is also more convenient,because it does not need the ... |
