| 摘 要： | 随着干扰技术的发展,GPS抗干扰性能差的缺点日益突出,对于能有效用于工程应用的抗干扰方法的研究显得尤为重要。空时二维抗干扰方法是GPS接收机抗干扰技术上的重大突破。在已给空时二维自适应滤波的模型及原理的基础上,通过对自适应约束准则的分析及选择,进而对不同情况下的空时自适应滤波权值的频率-角度响应进行了数字仿真和分析,得出了空时自适应滤波抗干扰的一些有益结论及合理解释。

| Abstract: | Along with the development of jamming technology,it is obviously that GPS shows a poor performance on interference suppression,and the study of an anti-jamming technique which can be efficiently used in engineering application becomes more important.space-time adaptive processing(STAP) technique is a great innovation on anti-jamming for GPS receivers.The model and theory of space-time adaptive processing are given,and through an analysis and selection of adaptive constrained rules,the frequency-angle respon... |
