Abstract:
A novel optimization technique known as the
microparticle swarm optimizer ( PSO) is proposed for high-dimensional
microwave image reconstruction. With the proposed
PSO, good optimization performance can be obtained especially
for solving high-dimensional optimization problems. In addition,
the proposed PSO requires only a small population size to
outperform the standard PSO that uses a larger population size.
Our simulation results on the reconstruction of the dielectric
properties of normal and malignant breast tissues have shown
that the PSO can perform quite well for this high-dimensional
microwave image reconstruction problem.
