Abstract

In the wideband transmission digital beamforming technology, due to the aperture crossing phenomenon, we cannot simply replace the delay with digital phase shifting. Commonly used fractional delay methods include the windowing method, VFD filter and other methods, but the fractional delay filter often has a serious hardware resource consumption, which is not conducive to the realization of multi-channel beamforming on a single chip. In this paper, a time-delay beamforming method based on DDS parameter control is proposed, and the system structure of emission beamforming is further optimized on the basis of which to save more resource consumption.
