摘要
介绍了数字多波束技术的应用。重点分析了目前较为常用的3种数字多波束技术信号处理的自适应算法并对各种算法进行了比较。自适应算法的选择决定了在环境变化时,波束自适应控制能力和反应速度,以及实现算法所需硬件的复杂性。
The application of digital multi - beam technology is introduced in this paper. Three kinds of adaptive algorithm of signal processing of digital multiple beams technology, which are in common use now, are in detail analyzed and compared. The selection of adaptive algorithm determines the adaptive beam control capability and the reaction rate when the condition changes, as well as the hardware complexity for the algorithm implementation.
