DOD and DOA Estimation for Bistatic Co-Prime MIMO Array Based on Correlation Matrix Augmentation
International Conference on Control Automation and Information Sciences(2019)
摘要
This paper mainly deals with the problem of joint DOD and DOA estimation for bistatic co-prime array by forming two augmented correlation matrices. Firstly, according to the difference co-array of co-prime transmitting array, an augmented transmitting correlation matrix is constructed to serve for DOD estimation by one-dimension MUSIC. Afterward, a two-step augmentation method based on transmitting and receiving difference co-arrays is proposed to generate an augmented transmitting/receiving (T/R) correlation matrix which is utilized to calculate the paired DOAs by one-dimension MUSIC with the estimated DODs. Numerical simulations demonstrate the effectiveness of the proposed algorithm.
