A kind of neighbours that beam scanning is combined with DOA discovery and accuracy alignment method

The invention discloses neighbours' discoveries and alignment scheme that a kind of beam scanning is combined with DOA, it is related to the discovery of the neighbours in microwave phased antenna systems non-stop layer networking and beam alignment.Each node switches first with antenna in the program and fixed beam figuration realizes that thick beam scanning and neighbours are found, then further realizes accurate wave beam using DOA estimation and digital beam forming and is aligned.This scheme can be applied in microwave non-stop layer constructing communication network, solves neighbours' discovery and accurate wave beam alignment issues, effectively reduces hardware and software algorithm complexity, can satisfy the demand of vehicle-mounted, carrier-borne and unloaded microwave equipment multinode non-stop layer networking.
