Dallan Byrne

Dallan Byrne received the B.Eng. degree in electronic and computer engineering in 2007 at the National University of Ireland, Galway. He received his Ph.D. at the same institution in 2012 on the topic of cancer detection using ultrawide-band radar techniques. Since 2012 he has been a research assistant at the University of Bristol, UK. As a member of the microwave breast imaging team, his work focuses on the advancement of radar and DSP techniques for clinical breast scanning. His research interests include microwave and radar imaging, and the biomedical application of signal processing techniques.

    Compound Radar Approach for Breast Imaging

    This paper considers the problem of detecting tumour targets within breast phantoms using multistatic radar. To accurately image small, potentially cancerous targets, a significant number of multistatic channels are required in order to adequately calibrate-out unwanted skin reflections and increase immunity to clutter. However, increasing the density of antennas within an array is inevitably limited by the geometry of the microwave elements designed for biological applications. A novel compound imaging approach is presented to overcome these constraints and improve the imaging performance of a multistatic radar modality. Experimental data is acquired to evaluate the algorithm using constructed phantoms of varying complexity.
