| 摘 要： | 空时处理应用于导航接收机抗干扰可以有效抑制多种干扰,但会不可避免地导致导航信号的失真.这样的失真如果严重影响接收机性能,则空时抗干扰的应用将会受到很大限制.深入分析空时处理对导航信号的影响,指出空时处理可以可靠地应用于导航接收机抗干扰中,但要选取合适的最优准则和约束条件,使空时信号处理保持线性相位.

| Abstract: | STAP(Space-time adaptive processing) technique has a good performance on interference suppression,while the distortion of navigation signals is induced inevitably.If the distortion has a great influence on receiver performance,the application of STAP anti-jammer will be limited seriously.The important issue is analyzed.It is pointed out that STAP could apply to anti-jamming reliably in appropriate optimal criterions and constraints which make navigation signals remain linear phase. |
