OPTIMIZATION OF 2-DIMENSIONAL RADOME BORESIGHT ERROR PERFORMANCE USING SIMULATED ANNEALING TECHNIQUE

In this paper a systematic approach to radome design is presented. The problem is formulated as a global optimization procedure such that th e radome performance is optimized by properly adjusting the thickness of the radome layer over the entire radome surface. In this approach t he thickness profile is parameterized via B-splines representation. Si mulated annealing technique is applied to finding the best thickness p rofile so that the maximum boresight error is reduced as small as poss ible over the entire range of the antenna look angle. A two-dimensiona l design example is given. The best possible thickness profile is foun d and the boresight error is reduced considerably compared to that due to a uniform layer. The method is general and can be applied without difficulty to other realistic three-dimensional radomes of arbitrary s hapes.
