✦ Synopsis

In this Letter we suggest an iteratii:e imaging technique based on a simulated annealing (SA) algorithm for a perfectly conducting cylinder. It is numerically shown that an imaging technique that uses SA does not require prior knowledge regarding the center and the shape of an object9 whereas one that uses conuentional gradient algorithms does require this knowledge regarding a scatterer. It is also shown cia numerical simulations thut this technique is very insensitive to noise in the scatteredfield and is not much afpcted by the observaiion locations.

The unit vector s was chosen arbitrarily, and ˆ0 z f L. The precision was set to 1.0 = 10 y3 . For each L, the function T was evaluated at 2 L 2 observation points. This is L in accordance with the demands of MLFMA. The results are presented in Table 2. In the table, entries marked ''direct'' refer
