“…In this case, the principal source of leakage becomes e lectro m agnetic (EM) coupling between the two arrays, which can be reduced to an acceptable level simply by increasing the physical separation between them. For example, with a separation of a few metres between edges of a Rx and Tx array in the same plane, isolation values of greater than 80 dB can be readily achieved over a wide range of frequencies and array scanning angles [ 27 ]. With this level of isolation, high-power HPAs can be used on the Tx array without affecting simultaneous reception on the separate Rx array.…”

The evolving role of modern navies has required increasingly higher levels of capability in the Radio Frequency (RF) shipboard systems that provide radar, communications, Electronic Attack (EA) and Electronic Support (ES) functions. The result has been a proliferation of topside antennas and associated hardware on naval vessels. The notion of MultiFunction RF (MFRF) systems has drawn considerable interest as an approach to reversing this trend. In a MFRF system, RF functions are consolidated within a shared set of electronics and antenna apertures that utilize Active Electronically Scanned Array (AESA) technology. This paper highlights a number of issues to be considered in the design and implementation of a naval MFRF system. Specifically, the key requirements of the RF functions of interest are first reviewed, and MFRF system design trade-offs resulting from costs and/or performance limitations in existing hardware technology are then discussed. It is found that limitations in hardware technology constrain the implementation of practical MFRF systems. MFRF system prototype development programs that have been conducted in other countries are described. MFRF resource allocation management is identified as an important future research topic.
