ABSTRACT

Wideband beamforming have been widely used in many applications such as: radar, radio astronomy, communications, sonar and microphone arrays. One of the powerful wideband beamforming techniques that is capable of achieving a high selectivity over a wide bandwidth is the nested array (NA) beamformer. Such a beamformer consists of nested antenna arrays, 2-D spatio-temporal filters, and multirate filterbanks.  Speed of operation is bounded by the speed of the hardware implementation.

This seminar presents the use of a systematic methodology for design space exploration of the NA beamformer basic building blocks. The efficient systolic array design of each block was selected for hardware implementation. The proposed systolic array designs and the conventional designs were implemented in FPGA hardware to verify their functionality and compare their performance. The implementations results confirm that the proposed systolic array implementations are faster and requires less hardware resources than the published designs.
