Low angle direction of arrival estimation by time reversal

Xiaolu Zeng, Minglei Yang, Baixiao Chen, Yuanwei Jin

ICASSP 2017accepted

In a low angle target parameter estimation scenario, the backscattered signals from targets are distorted by clutter and multipath, which degrades the performance of direction-of-arrival (DOA) estimator significantly. This paper presents a novel method using time reversal (TR) technique and coherent…

A new array geometry for DOA estimation with enhanced degrees of freedom

Minglei Yang, Alexander M. Haimovich, Baixiao Chen, Xin Yuan

ICASSP 2016accepted

This work presents a new array geometry, which is capable of providing O(M2N2) degrees of freedom (DOF) using only MN physical sensors via utilizing the second-order statistics of the received data. This new array is composed of multiple, identical minimum redundancy subarrays, whose positions follo…
