ABSTRACT
In ultrasonic computerized tomography imaging of concrete structures, Particle Swarm Optimization (PSO) algorithm may produce premature and lead to poor imaging results which always can not meet requirement. An improved PSO inverse algorithm based on Simulated Annealing (SA) algorithm is presented here. The imaging accuracy can be enhanced by combining the PSO and SA algorithm which can take advantage of the ability of jumping out of the local optima in SA and keep the capacity of smart and global search in PSO. Numerical simulation demonstrates that higher imaging quality is obtained and the embedded object is clearer.
