Abstract : An interactive computer graphics antenna gain pattern computation and display program for real-world antenna systems is presented. The use of the program as a teaching tool at the Naval Postgraduate School is discussed. Methods for applying the program for the synthesis and design of complex antenna systems are indicated. Research applications include techniques for rapid inspection of gain equations of newly developed antennas. A ship motion model is developed for studying the effects of electrical geometry variations caused gy ship motion in heavy seas on maritime antenna systems and a dynamic presentation of pattern variations is made.
