One-bit signal single snapshot direction-of-arrival estimation method and related components

The invention discloses a one-bit signal single snapshot direction-of-arrival estimation method and related components. According to the method, the characteristics of frequency modulation one-bit quantitative sampling and one-bit signal single-snapshot direction-of-arrival estimation are combined; echo signals received by the front end of an array radar system are firstly subjected to dechirpingprocessing and frequency shift processing, then frequency modulation one-bit quantization is carried out, AD sampling is carried out, and then direction-of-arrival estimation of a detected target is carried out in a signal processing system at the rear end of the array radar by adopting single sampling snapshot. One-bit quantitative sampling at the front end of the array radar is highly matched with single-snapshot direction-of-arrival DOA estimation of one-bit signals at the rear end of the array radar; the structure of an array angle measurement radar system can be simplified, the cost of data acquisition, transmiss
