Fast DOA estimation using co-prime array

A new method is proposed to estimate the direction-of-arrivals (DOAs) of multiple narrow-band signals using a co-prime array (CPA). The CPA is divided into two uniform linear arrays (ULAs) and two polynomials are derived by utilising the unitary transformation technique on the covariance matrices of...
