In this paper we examine the geometry of a number of navigation schemes for guiding a pursuer from a fixed initial position to a final target position. We explicitly characterize the optimal pursuer trajectories for the given problems in terms of minimizing the error in an unbiased estimate of the target position from successive bearing measurements made along the trajectory.

Background and Aim: Management of children’s behavior is fundamental to a successful and effective dental treatment for children. This study aimed to evaluate the perceptions of dental students towards behavior guidance techniques in pediatric dentistry. Materials and Methods: This cross-sectional study was carried out on dental students from three different levels of education. A questionnair...

When a detector sensitive to the target plume IR seeker is used for tracking airborne targets, the seeker tends to follow the target hot point which is a point farther away from the target exhaust and its fuselage. In order to increase the missile effectiveness, it is necessary to modify the guidance law by adding a lead bias command. The resulting guidance is known as target adaptive guidance ...
