Embodiment Construction

[0019] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0020] A serial-parallel composite digital beamformer design method, comprising the following steps:

[0021] In an array antenna system with A rows and B columns, M*N digital beams need to be formed, where M*N digital beams are divided into M groups, and M groups of digital beams need to be processed. The distance units are R 1 , R 2 , R 3 ,...,R M-1 , R M , and R 1 ≤R 2 ≤R 3 ≤...R M-1 ≤R M .

[0022] Wherein, the intra-group processing distance units of the M groups of digital beams are the same, and the inter-group processing distance units may be different.

[0023] The serial-parallel composite digital beamformer mainly includes data buffering an...

Abstract

The invention discloses a design method of a series-parallel composite digital beam former, mainly solves the problem of resource waste generated by digital beam forming under the condition of non-uniform airspace coverage, and provides an efficient digital beam forming method. Compared with a traditional method, the method has the advantages that a software algorithm can be optimized and the hardware resource utilization rate can be increased when beams are non-uniformly divided in a coverage airspace.

Description

technical field [0001] The invention relates to the technical field of digital signal processing, in particular to a design method for a serial-parallel composite digital beamformer. Background technique [0002] Existing beamformers usually use a parallel structure to simultaneously form multiple digital beams for uniform coverage of the airspace. In the case of non-uniform coverage in the airspace, using a parallel structure to simultaneously form multiple digital beams will cause unnecessary waste of resources. Contents of the invention [0003] Aiming at the problems in the above technical background, the present invention provides a serial-parallel composite digital beamformer design method, which mainly solves the problem of resource waste caused by digital beamforming in the case of non-uniform coverage in the airspace, and provides an efficient Digital beamforming method. [0004] In order to achieve the above object, the technical solution adopted in the present...
