Abstract

A common requirement in electro-optical surveillance or weapon delivery systems is to point at or scan a target from a moving vehicle. The required gimbal commands are developed and presented for a variety of gimbal configurations using position and / or velocity information such as is commonly available from an onboard INS or GPS system. Both pointing angle and angular rate approaches are considered along with considerations for back-scanning with, for example, a fast steering mirror. The results are also shown to be applicable as a rate-aiding enhancement to many closed-loop tracking systems. While no fundamentally new techniques are presented in this paper, an organized approach to a common problem is presented along with some control system implementation issues.
