摘要
提出了一种新的算法-峰值相减法,用于在并行捕获中消除互相关干扰.仿真表明,该算法可以至少消除95%的互相关干扰,在整个定位算法的第一步消除互相关干扰,减轻了后面算法消除互相关干扰的负担,具有一定的实用性.
This paper represent a new algorithm called Peak Difference,which is employed in the parallel acquisition station to mitigation the cross correlation signals. The simulation tells us that the more than 95 percent cross correlated signal can be better excluded with no complexity. This method is used in the first step of mitigation of cross correlated signal,which alleviate the burden of the successive steps in position process.
