Description
Summary:The necessity of gimbaled seeker arises to provide the capability of scanning a large area, as the field of view (FOV) of the seeker alone is limited due to many reasons. In this work, a generalized method of spiral scan pattern generation has been proposed. This will be very efficient in terms of control efforts, scanned area, overlapping and scanning time. Also, a scheme has been given which will enable the seeker to start scanning from its nearest position when target is lost during tracking. Presented seeker is able to distinguish the target being illuminated with coded laser pulses and scans wide area in small time with less control effort.
