Zusammenfassung: | According to the self-adaptive anti-interference method based on hybrid beam forming, analog beam forming and digital beam forming are combined, and the problems that in the airspace anti-interference technology, hardware composition is complex, the size and weight are large, the data dimension is high, and the real-time performance is poor are solved by means of the advantages of the analog beam forming and the digital beam forming. Specifically, an array antenna is divided into a plurality of sub-arrays, phase shifting is carried out on received signals of array elements in the sub-arrays in an analog domain, and beam gain is formed in a target signal direction; and performing down-conversion and AD conversion on the signal formed by the sub-array beam, performing adaptive beam forming on the signal formed by the sub-array beam in a digital domain, and suppressing an interference signal. According to the scheme, a hybrid beam forming scheme is adopted, conventional beam forming is carried out on sub-array s |
