RAM PLASTIC PERISCOPE PLASTIC HEAD

A submarine periscope is modeled as a cylindrical metal reflector poking out of a rough sea. The time variant component of its radar cross section (RCS) behaves as a Swerling Type I target whose magnitude can be reduced by application of RAM. Various options exist for incorporation of RAM into an outer periscope head which can be retrofitted to equipment already at sea. These options include encapsulating or compound molding RAM into a finished part. Injection molding the head from a resistive plastic matrix is another possibility. The research herein looks at detailed mechanical and electrical requirements, and methodology for incorporating RAM into a plastic periscope outer head. As part of this research, flat panel samples of material are fabricated and electrically tested. Consideration is given to cost, producibility, and combat survivability of the finished parts.
