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.

Research on Calibration Method for Receiving Channel in DBF;

Implementation of DBF Based on CMA in the Multi-antenna SDR Platform;

Analysis of Effects to the DBF of Meterwave Antenna with Ground Reflection;

pulse chasing and digital beam forming(DBF) are analyzed;and relation between receiving beam direction and transmitting beam direction as well as mutual distance between receiver and transmitter are presented.

In order to resolve the problem,a new method which combines digital beam forming(DBF) technology with the foregoing method to increase measurable elevation range is presented in this paper.

It is showed that digital beamforming(DBF) is a powerful technique for enhancing radar antenna performance.

The digital beamforming(DBF) and multitarget tracking of plane array are researched based on mathematical analysis and computerized simulation.

The high speed analog to digital converters(ADC) and advanced digital signal processors(DSP) make the smart antenna with digital beamforming(DBF) to be practical.
