MICROWAVE IMAGING A BURIED OBJECT BY THE GA AND USING THE S11 PARAMETER

This paper explores the feasibility of microwave imaging a buried object by the GA and using the S11 parameter of a radiation antenna rather than data of the scattered electromagnetic field. To improve the efficiency of the GA-based algorithm, a technique of limiting the location of the buried object prior to the implement of the GA is proposed, and the GA is parallelized and executed on a PC cluster. A few numerical examples are presented, in which the dimension and location of a 3-D object buried in the earth are recovered. Results validate the proposed GA-based microwave imaging algorithm.
