Abstract :
Position perturbation of the array elements is used for reducing the sidelobe structure in the radiation pattern of phased arrays. Results of computer simulations showed good improvements in the side lobe structure as compared to the equal size linear array. A quantitative measure of the improvement is postulated. Results are compared with those obtainable from the technique of adding 2 auxiliary elements.
