Antenna Array Beamforming Technology: Enabling

In this paper, we propose the exploitation of array beamforming technology in high-speed aeronautical communication applications, e.g., the integrated Network Enhanced Telemetry (iNET) system. By flexible steering of beams and nulls, an array can enhance desired signals whereas the undesired signals such as interference and jammers are suppressed. The proposed adaptive beamforming technology is...

Equal Gain Beamforming in Rayleigh Fading Channels

Precoding techniques with limited feedback information can achieve satisfactory performance while the amount of feedback information is kept small. In this paper, we analyze the theoretical performance of equal gain precoder and find that its performance is at most 1.049 dB worse than the optimal precoder no matter how the number of transmit antennas increases. Moreover, we found that the equal...

Phased array ultrasonic imaging using an improved beamforming based total focusing method for non destructive test

One of the novel ultrasonic phased array based scanning methods for ultrasonic imaging in non-destructive test is total focusing method (TFM). This method employs maximum available information of the phased array elements and leads to an improved defect detection accuracy compared to conventional scanning methods. Despite its high detection accuracy, TFM behaves weak in distinguishing the real ...

Quantization Analysis for Reconfigurable Phased Array Beamforming

In reconfigurable phased array radars beamforming is performed in the digital domain. Digital implementation can be carried out using finite precision and infinite precision representation of the phased array signal. We consider finite precision representation, since it takes considerably less implementation resources compared with the infinite case. In this paper we analyze quantization effect...

Farfield Array Weight Redesign for Nearfield Beamforming

This paper presents a new method for nearfield linear array beamforming that achieves a desired beampattern (as a function of direction) at any nominal finite distance from the array origin. Given a set of array weights which achieves the desired beampattern for farfield sources, we device a linear transformation to obtain another set of array weights which achieves the same beampattern for sou...
