Abstract :
Cosec square beam have receiving uniform echo performance at the same height but different distances. The level exceeds that of traditional cosec square beam. In order to restrain interfere of multipath reflect, the beam must be cut sharply on the ground. Through setting appropriate fitness functions and choosing optimal optimization algorithm, a method of over cosec square-beam shaping with sharp cut off is presented in this paper, which can obtain result that satisfies the designed requirements of engineer.
