Özet:

In basic guidance applications, the line-of-sight (LOS) and line-of-sight rate information, which can be provided using a passive seeker, are enough to steer the missile to the target. However, if one wants to augment the guidance algorithm, further information regarding the engagement and/or target is needed. Unlike passive seekers, active and semi-active seekers may provide such information. Nevertheless, if the missile is equipped with a passive seeker, those parameters need to be estimated. Various methods are available in the literature for the estimation, which use Kalman Filters, lacking observability if the missile does not accelerate. In this thesis, using a brute force method, a new algorithm for estimating target parameters is proposed; which does not need missile acceleration for observability.
