Application background Beamforming is one of the main branches of the array signal processing, can be widely used in the fields of radar, communication, sonar, navigation, speech signal processing, earthquake monitoring, geological exploration, radio astronomy and biomedical engineering, etc.. Key Technology beamforming, also known as spatial filtering. The time domain FIR filter is similar to that of linear filter. The array processing is a kind of spatial sampling and processing technology. ; the structure of the array is different, mainly divided into linear array, circular array, triangular array, L array, spherical array, etc..
