摘要

提出了一种适用于任意阵列的频率与二维DOA联合估计算法。该算法同时利用空域采样与时域采样构造二维时空矩阵

基于2D-ESPRIT方法进行二维参数估计

仅需3个校准阵元就可通过M个阵元估计出M个独立信源的载波频率、方向角和仰角

无需二维谱峰搜索

计算量较小。仿真实验验证了算法的有效性。

Abstract

A joint estimation method of frequency and 2D（two-dimensional） direction of arrival was proposed for arbitrary array. Spatial domain sampling and time domain sampling were used synchronously to construct space-time cross-correlation matrixes

and 2D-ESPRIT method was utilized to estimate the 2D parameters in this method. Without spectral peak searching and complex computation

and only needing three guiding sensors

the carrier frequency

azimuth and elevation angles of M independent sources could be estimated by using M sensors. The effectiveness of this method is demonstrated by some simulation examples.
