Abstract

A complex digital signal processing system like the LFAA tile beamformer requires extensive simulations to test its compliance with the system specifications.

A Matlab simulator, composed of a general purpose signal generator, a simulation pipeline for the actual processing, and a set of analysis tools to extract the significant parameters from the processed data has been designed and tested.

The simulator has been used to test various parameters, as added digital noise, calibration capabilities, spectral response, channel to channel insulation and beamforming losses.
