卫星导航抗干扰领域,为克服空时联合处理计算复杂度高及抗干扰性能上升空间低的问题,提出一种空频联合处理机制。通过理论与仿真分析证明该处理机制具有更好的抗干扰性能。同时通过对3种常用自适应计算方法的对比,在收敛速度及计算复杂度两个方面为这种空频联合处理机制选择最佳计算方法,使其性能得到最大发挥。

In order to solve the problem of high computational complexity and low anti-interference ability of space-time joint processing, a space-frequency joint processing mechanism is proposed in the field of satellite navigation and anti-jamming. The theoretical analysis and simulation show that the mechanism has a better anti-jamming performance. At the same time, through the comparison of three commonly used adaptive calculation methods, the best calculation method is chosen for the space-frequency joint processing mechanism in two aspects of convergence speed and computational complexity, so that its performance can be maximized.
