Abstract

Compact seeker design is important in missile application. Main reason is the challenging allocation of drag coefficient reduction, performance/mass ratio and flight motor performance. All of these factors are tried to be optimized in an iterative manner for a couple of periods. However, because of the disturbing nature of the vibration of missiles, gimbals and vibration isolation/suppression methods are popular. Depending on the frequency of the vibration, old fashioned gimbal approaches can end up in an increase of the missile diameter to embody complex mechanisms to eliminate vibration effect. New proposed methods are vulnerable to jitter on image. In order to keep the diameter of the missile at certain level, complex gimbal subsystems can be removed from seeker. Not to be affected from the jitter on image, piezo actuator system can be used. In this study; an optical design and production of the camera module is conducted. Performance of the camera module is analyzed in simulation and tested in laboratory. After that, target is simulated in the collimator system to illustrate the performance of the module. Later, camera module performance is tested under the vibration test profile with automatic target acquisition algorithm to compare results of the system objectively. Finally, analyzes are performed to show piezo actuator effects on vibration test profile.
