“…In direct holography, the complex scattered field is measured over a selected aperture in the near field using Vector Network Analyzer (VNA) to image the objects. A majority of the holographic approaches for cancer detection [4][5][6][7] are based on direct holography. This technique is very expensive and computationally complex as due to its mathematical dependency on vector calculations.…”

“…In this study, all datasets were collected by positioning the phantom at 144 different angles, which emulates 144 different scan locations. After the phantom contents had been rotated into a particular angular position, a stepped frequency continuous wave with The datasets were used for image reconstruction using the multistatic approach described in [23].…”

The detailed design equations and antenna parameters for a directional antenna for breast imaging are presented in this paper. The antenna was designed so that it could be immersed in canola oil to achieve efficient coupling of the electromagnetic energy to the breast tissue. Ridges were used in the horn antenna to increase the operating bandwidth. The antenna has an exponentially tapered section for impedance matching. The double-ridged horn antenna has a wideband performance from 1.5 GHz to 5 GHz (3.75 GHz or 110% of impedance bandwidth), which is suitable for breast microwave radar imaging. The fabricated antenna was tested and compared with simulated results, and similar bandwidths were obtained. Experiments were conducted on breast phantoms using these antennas, to detect a simulated breast lesion. The reconstructed image from the experiments shows distinguishable tumor responses indicating promising results for successful breast cancer detection.

The images generated by the proposed method show that multistatic holography is capable of forming spatially accurate images in real-time with signal to clutter levels and contrast values higher than other published monostatic and multistatic cylindrical radar reconstruction approaches. In comparison to the monostatic holographic approach, the images generated by the proposed multistatic approach had SCR values that were at least 50% higher. The multistatic images had CCR and TFRR values at least 200% greater than those formed using a monostatic approach.
