Beam Domain Localized Adaptive Beamforming for Fully Digital Active Array Radar

Multi-beam Adaptive Beamforming Using a C-band Receiver Array and a Frequency-domain Digital Beamformer

This paper introduces a novel architecture of a multi-beam adaptive beamformer for SDMA (space division multiple access) applications. Combined with a 5.8 GHz eight-element RF front-end, digital beamforming performance using the proposed frequency-domain multi-beam beamformer is demonstrated in post processing. The DOA estimation based on the ESPRIT algorithm and simultaneous dual-beam forming ...

Novel Method of Realization of Scalable VLSI Adaptive Digital Beamforming Architecture for Phased Array Radar

This This paper describes a novel method for the hardware Design and realization of adaptive filter for the application of Adaptive Digital beam former suitable for FPGAs. The planar phased array configuration considered in this case is sixteen element array. Design approach followed is modular design and each one of the modules is reused to make the sixteen element planar array configuration. ...

Adaptive Digital Beamforming Antenna Array for High Speed Communications

The rapidly increasing demand for PCS has provided the impetus to design adaptive antenna arrays to improve spectral efficiency and enhance system capacity. With increasing data rate in some PCS application like DECT( Digital European Cordless Telecommunications), higher BER would degrade the system performance further. An adaptive antenna array testbed using 12 elements was built to evaluate i...

Adaptive VLSI Architecture of Beam Former for Active Phased Array Radar

This paper describes architecture for a digital beam former developed for 16 element phased array radar. The digital beam former architecture includes the complex operations such as down conversion which is done in parallel for the signal coming from each of the antenna elements and the filtering. A high performance FPGA is employed to perform these operations. An echo signal of 5 MHz riding on...
