Estimation of Breast Tumor Location using Phase Information and Received Signal Delay

In this article, a new method is proposed to find tumor's location. This process is based on the arrangement of sensors; the phase and distance to the cancer are given as well. Extraction of tumor distance and phase by Snell's law is the number of received pulses and the delay of receiving Signal. The transmitter antenna is in a fixed position, and the receiver rotates at a certain angular velocity around the tissue. Considering this information, a package solution in polar coordinates is presented. Meanwhile, angle and range information are extracted. Then the maximum probability estimate of the target location is given. This paper applies experimentally to simulated random data.
