一种新的信号多参数估计方法
A NOVEL METHOD FOR SIGNAL PARAMETERS ESTIMATION
-
摘要: 本文基于圆阵列及其输出时延提出了一种空间信号频率、方位角和仰角的联合参数估计新方法。此方法回避了多维谱峰搜索和参数配对,克服了在短数据时离散傅立叶变换测频分辨率低和性能差的不足。计算机模拟证实了该方法的有效性。

Abstract: Based on uniform circular array and its elements output signal delay, a novel method for estimation of spatial frequency, azimuth and elevation is presented. Without any spectral peak search and parameters pairing, the resulting method is computationally efficient with high resolution and small variance, even in the short data length. Computer simulation demonstrates the effictiveness of this method. -
