    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.
