Abstract

In this paper a modified Gaussian pulse stimulus is employed to improve the accuracy of tumor detection inside breast phantom for 2D reconstructed image results in cylindrical setup of the microwave imaging system. This pulse shaping puts more energy at higher frequencies in contrast with conventional Gaussian pulse shaping in the impulse Radar. Hence a wider bandwidth is available to achieve higher accuracy for precise spatial localization. In the present article a simulated cylindrical setup of the microwave imaging system with a modified stimulated pulse is generated. The main purpose of this paper is employing a new stimulating pulse to detect a tumor from a biological phantom for 2D visualization of time-domain results. In order to achieve the goal, the advantages of generating a novel confocal image-reconstructing algorithm based on back-projection method is employed. The advantage conferred by “ high resolution imaging” is that more energy is used at reflected signal than with conventional confocal imaging, and subsequently a relatively lower spatial resolution in identifying the reflected signal is achieved. Simulated results are presented to validate the effectiveness of the proposed method for precisely calculating the time-dependent location of targets.
