The tests which are conducted to observe the behavior of a system in realistic operational conditions have great
importance in order to determine its performance prior to the relevant field studies. These studies provide the designers
with deciding on the necessary design updates and they also lead to reduce the total development cost in a significant
level. In order to execute the mentioned tests, the motion simulators being able to simulate the motion characteristics of
the system in a realistic environment are needed. Looking at the available simulators in the world, it is seen that different
system configurations have been used in accomplishing the desired test objectives. In these systems, not only the
mechanical designs differ from each other, but also the control systems are employed in various structures. In this study,
the properties of widely-used motion simulators designed for infrared camera systems are evaluated with regard of the
certain design issues. Also, their advantages and disadvantages are emphasized.
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.
