Abstract
In guided munition applications, it is a priori to detect the intended target correctly and then to track it until the termination of the engagement. However, especially high angular rates of the munition carrying an infrared (IR) type camera cause the target image on the detector of the camera to blur. This, in turn, results in losing the correct target information and even in missing the target. Therefore, it is required that the blur problem be handled carefully in an IRtype camera design process. In this study, the blur problem of an IR-type gimbaled camera operating on a guided munition is dealt with and the net field of view of the camera is determined for its different configurations. In the calculations, the roll rate of the munition is taken into consideration because of the fact that it is much greater than its counterparts in the yaw and pitch directions. Afterwards, the roll rate limit causing no blur is obtained and the ways that can be applied to avoid this severe condition are proposed.
