针对三机无源定位二维布阵优化问题,提出了基于有效定位区面积最大准则的最优布阵方法.文中以三机时差定位、频差定位及时频差定位为例,描述了三机无源定位模型,接着基于克拉美-罗限引入了有效定位区的概念,并以其面积最大作为布阵优化准则,通过仿真研究了二维布阵优化问题.仿真结论反映了三机时差、频差及时频差定位体制的不同特性,具有较强的实际指导意义.

For optimal two-dimensional(2-D) sensors placement for 3-aircraft passive location system,a method based on maximum area principle is proposed.In this paper,3-aircraft time difference of arrival(TDOA) location,frequency difference of arrival(FDOA) location and hybrid TDOA/FDOA location are taken as examples.First,the basic description of passive location models is given.Then,the concept of effective location region is introduced based on Cramer-Rao Lower Bound(CRLB).Besides,the principle of maximum effectiv...
