BRATUMASS Antenna Positioning Optimization with Genetic Algorithm

Using the difference of dielectric constant between malignant tumor tissue and normal breast tissue, BRATUMASS (Breast tumor microwave sensor system [1]) can determine the detected target properties by analyzing the properties of target tissue back wave obtained by near-field microwave radiation. The practical experiments show that the target space and records of antenna corresponding position displacement when the antenna close contact with skin tissue will be changed, which might lower the quality of the inversion imaging of result. So, the target space characteristic data is introduced in order to eliminate the effect of the displacement. This paper presents a method of antenna relative position placement optimization using genetic algorithm and performs its feasibility with optimized examples.
