Abstract
An active microwave seeker for missile guidance against ships or permanent and targets. Frequency agility and pulse time compression are employed as means to provide a capability for tracking small targets in heavy sea clutter, to reduce target angular scintillation, and to reduce susceptibility to enemy jamming. The seeker tracks a selected target in yaw and range, and keeps its antenna pointed toward the target in pitch by use of its own altitude control.
