摘要

针对已知脉冲期望信号转换时间的具体情况,讨论了自适应阵列在通信中的应用。根据这些信息,可以确定在期望信号上发射的自适应天线权重。先前提出的方法在热噪声功率电平和干扰功率电平随时间恒定时工作良好,即场景是平稳的。但是,当环境不是稳定的时候,这些方法会严重退化。作者提出了对传统处理的扩展,以允许在热噪声和/或干扰功率水平的大变化下实现接近理想的性能。计算机模拟验证了该算法即使在功率电平非常大(>20 dB)的变化下也是有效的。

Pulsed communication adaptive array processing
The application of adaptive arrays to communications is addressed for the specific case of known pulsed desired signal transition times. From this information, the adaptive antenna weights that beam up on the desired signal can be determined. Previously proposed approaches work well when the thermal noise power level and interferer power levels are constant versus time, i.e., the scenario is stationary. But these approaches degrade seriously when the environment is not stationary. The authors present extensions to conventional processing to allow for near-ideal performance with large variations in thermal noise and/or interferer power levels. Computer simulations verify that the algorithm is effective even for very large (>20 dB) changes in power levels.<>
