The advanced multifunction RF concept
TLDR
This paper describes a proof-of-principle test-bed that is being developed to demonstrate the Advanced Multifunction Radio Frequency Concept, a wide-band generic active array antenna architecture that has the ability to transmit and receive multiple simultaneous independent beams for radar, EW, and communication functions.

The Advanced Multifunction RF Concept (AMRFC) Test Bed
TLDR
In this program, hardware and software that emulate Emission Control, Normal, and Combat scenarios have been successfully combined in an active Proof of Principle demonstration at NRL's Chesapeake Bay Detachment (CBD).
Integrated Topside - integration of narrowband and wideband array antennas for shipboard communications
TLDR
The integration of the two arrays provides redundancy, multipath mitigation, frequency diversity, the potential to employ spatial separation to achieve the desired number of links within the existing frequency constraints, and the ability to allocate receive assets to enhance the frequency management of the ship to prevent interference and contention.

An Azimuth Measurement Algorithm for Mechanically Rotating Pulse Doppler Radars.
Abstract : For a mechanically rotating pulse Doppler radar having only a single main beam, an algorithm is presented that obtains an estimate of a target's azimuth angle using echo data obtained over…
Clutter filtering and processing techniques for EMI detection and angle measurement in pulse Doppler radars
TLDR
A filtering methodology is presented for optimally suppressing the cluttercontained in the received CDIs, thereby revealing EMI pulses contained in the data as well as the antenna scan modulation on the target echo.
