Case studies
PC-based SAS Processing Software for NURC
Bloomsbury DSP were asked by NURC to implement SAS processing in a user-friendly piece of standalone software. This has been completed and delivered to the centre. The software makes use of technologies such as wxWidgets, Python, OpenMP and Intel IPP to deliver a high-performance, simple to operate SAS processing reference for the ongoing research at the centre.
FPGA implementations of DPCA and Beam-Former for NURC
Bloomsbury DSP were asked by NURC to implement the DPCA micronavigation algorithm and a yaw stabilised beamformer for a synthetic aperture sonar using FPGA devices. Papers describing this work:
