On the base of summarising the digital beam null forming weighting structure,this paper presents three kinds of algorithms: amplitude and phase weighting,only phase weighting and compound control weighting,and then compares the three kinds of algorithms.

It is of great importance to study digital beam forming so as to overcome these problems.

This article introduces many kinds of ultrasonic transducers, transducer focus, and digital beam forming technology.

The principle and realization of digital multi-beamforming in linear arrays based on DSP;

A digital beamformer in medical ultrasound imaging systems conventionally requires that the returning signals received by transducers are sampled at a rate significantly higher than the Nyquist rate.

The radar digital beam forming and its mathematic analysis;

This paper introduces the principle,system composition and target indication of a fully digitized phased array radar in which digital beam forming techniques are used in receiving and transmitting.

In this paper, we analyze the methods of estimating DOA (direction of arrival) of target signals, then propose that it is available for using the digital beam forming technique in the projectile system.
