A new method for enhancing the performance on seeker tracking

Seeker is an important unit of the most tactical missiles, which detects and tracks the target, and provides missile the target´s position. The accuracy of the missile is highly relative to its seeker. A large number of seekers use a free gyroscope to keep the (Line Of Sight) vector direct at the target. Under the torque given by the precession coil, the gyroscope will precess or turn to a certain aspect, which keeps the LOS vector direct at the moving target. In this study, we analysis the gyroscope´s movement under the magnetic field created by running an electrical current through the precession coil. On this basis, we put forward a new method to increase the gyroscope´s precession speed by 27% by change the waveform of the precession current. With the higher precession speed, the seeker will be able to track faster moving target.
