Abstract:

This is the final technical report describing the design and development of a low-cost shipboard Mast Mounted CALL ALERT MMCA receiver system. Three prototype MMCA systems were built to demonstrate the feasibility of the design. These engineering models were configured so that they can be tested aboard ship to demonstrate the practical utility of the MMCA system. The equipment developed on this program depended heavily upon AILs patented fin-line 1 millimeter wave transmission techniques. By utilizing its fin-line techniques, AILs goal in the proposed program was to evolve a design that will ultimately minimize the cost of the system to the Navy. The proposed program was dedicated to this goal by planning, specifying and designing for low cost from the inception of the project. The MMCA system is intended to be used aboard Navy ships as a means of alerting appropriate personnel of the existence of an incoming signal in the Ka frequency band and of the approximate direction of its origin. The key components of this system are a A narrow-beam horn antenna, rotating in the azimuth plane, b A Ka-band receiver having the appropriate sensitivity and noise figure, and c A visual and aural display indicating the presence and direction of origin of the received signal.
