In this paper, a custom software defined radio that implements a smart antenna array is used in the task of real-time beamforming. Specific beamforming algorithms are implemented in FPGA, remotely controlled by a computer host. The antenna array is mounted in a metallic cylinder and tested in anechoic chamber. Experimental measurements highlight the efficiency of the algorithms implementation. Moreover,...
Two-dimensional (2-D) IIR beam filter applications operating in ultra wide-band (UWB) radio frequency (RF) range requires hardware capable of handling high speed real-time processing due to its operation bandwidth lies in megahertz or gigahertz range. Two-dimensional IIR beam forming is used mainly for applications such as communications, radars and detection of directional sensing. A systolic architecture...
This paper describes technology development efforts in support of phased-array digital beamforming at Applied Radar, Inc. The development efforts are aimed at increasing the bandwidth and dynamic range and enabling real-time throughput of multi-channel array data. This digital beamforming approach enables improved calibration, increased coverage through multiple receive beams, and adaptive processing...
