Compact seeker design by using piezo actuator in missile application

摘要

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