Beam forming is a signal processing technique used in antenna arrays for directional signal transmission or reception. Phased array radar is very important in modern radar development, and multiple digital beams forming technology is the most significant technology in phased array radar. Digital multiple beam forming on each antenna element about large phased array radar is impossible in proces...

communications spectrum from copper cables, optical fibres, microwaves, radio and electromagnetic compatibility. Our research concentrates on optical signal processing and networks, mobile communications, microwave techniques and radiation from ICs and PCBs [1]. A considerable (and particularly interesting) part of it is related to optical beam forming for phased array antennas, using optical r...

There is a need of Phased Array Antennas in applications such as wireless communication, RADAR systems. The radiation pattern for this type of antenna has to be narrower sharper in one direction and should have nulls in other directions. In order to achieve this, phased array antennas are designed in such a way so as to steer the beam in required direction automatically. One of the techniques d...

This paper deals with the possibilities of cancellation of unwanted signals by steering nulls of the pattern in the direction of arrival of signal while keeping the main beam to the desired direction. New iterative adaptive digital beam forming technique is presented here to enhance the conventional effectiveness of beam forming in common commercial application. Simulation and measurement resul...

This paper describes the audio component of a virtual reality system that uses remote sensing to free the user from body-mounted tracking equipment. Position information is obtained from a camera and used to constrain a beam-forming microphone array, for fareld speech input, and a two-speaker transaural audio system for rendering 3D audio. 1 Vision Steered Beam-Forming 1.

Digital Signal Processing (DSP) technology continues to transform radar systems and SDR systems. DSP technology has made it possible to improve dramatically the gains in radar sensitivity, range and image quality, as well as the gains in the SDR radio performance, data bandwidth and power efficiency. Next generation radars with SDR systems can leverage advancing DSP technology with advanced tec...
