| Abstract: | In this paper the advances in the cat's eye effect are reviewed.Some models of the cat's eye retro-reflectors are given,and the divergence angle resulting from the position deviation of the focus of the photosensitive surface is derived.The ratio of the echo power of cat's eye to that of the small diffuser is interpreted physically.Finally,some problems of the cat's eye effect in application are discussed. |

| Keywords: | cat's eye effect photoelectric reconnaissance detecting distance divergence angle |
