摘要
A single-bit quantized signal virtual domain statistic reconstruction-based co-prime array direction of arrival estimation method, comprising the implementation steps of: arranging a co-prime array and a single-bit analog-to-digital converter at a receiving end; arranging a co-prime array and a single-bit analog-to-digital converter at a receiving end; calculating an equivalent virtual signal corresponding to a co-prime array single-bit received signal; constructing an initialized single-bit quantized signal virtual domain augmented covariance matrix; on the basis of statistical correlation analysis between quantized and non-quantized signals, designing an optimization problem based on quantized signal virtual domain statistic reconstruction; and estimating the direction of arrival by using a virtual domain augmented covariance matrix corresponding to the optimized single-bit quantized signal. The method mainly solves the problem in the art of large difficulty and limited degrees of freedom in software and hardware implementation.
