RF System Performance Requirements
- Nov 01, 2017 -

InTop incorporates early research and development results for ONRs, particularly the Advanced Multipurpose Radio Frequency Concept (AMRFC) test platform and the Advanced Technology Development (MFM) development model (ADM). The AMRFC project, which originated in 1999, is a proof-of-principle demonstration project designed to develop general-purpose broadband RF apertures capable of simultaneously performing radar, RF System electronic warfare and communication functions with low signal characteristics. The goal is to significantly reduce the number of RF apertures on the mast, significantly reducing RCS, enhancing functionality and increasing bandwidth.

In fact,RF System AMRFC was the first test of the integrated mast concept, and the Navy Research Laboratory (NRL) and the industrial sector integrated the multi-function transceiver array, RF System exciter / receiver and Navy development resource allocation manager The The integrated work was completed at the AMRFC test bench at the Maryland Naval Research Laboratory in 2004 and fully demonstrated the electronic warfare (active and passive), communications and radar functions at the same time as the US Navy's R & D and acquisition departments

After AMRFC, ONR and NRL also launched the MFEW Future Navy Capability (FNC) project in FY2005 to promote key electronic warfare systems to full-scale engineering development. MFEW integrates seven aspects of performance requirements: frequency domain and airspace coverage; sensitivity; system response time (from signal detection to radiation source reporting); electromagnetic environment requirements (ship and ship outside the radiation source); signal arrival angle measurement accuracy; Antenna RCS; radiation source classification requirements (including false alarm rates); responsiveness to emerging specific threats. In addition, the ONR requires that the design must be modular, RF System open, scalable to meet the size and operational requirements of multiple platforms and to achieve incremental upgrades of the electronic warfare function, as well as in the Resource Allocation Manager (RAM) Real-time control integrated into the sensor / communication system.

The concept of dynamic control of radio frequency spectrum can be decomposed into a series of complementary objectives: to develop, integrate and demonstrate new multi-beam apertures and subsystems to support radio frequency multi-function (radar, electronic warfare, RF System signal processing and communication); through resource allocation Optimize the use of radio frequency spectrum and hardware, demonstrate the integration of a variety of carrier-based RF functions and real-time collaborative control; in cooperation with the Marine Systems Command, the InTop communication / sensor integration system into the ship design, Ship size and performance; by monitoring the control of electromagnetic interference to improve the availability of RF spectrum, RF System the development of new radio frequency spectrum combat concept.

The ultimate goal of the InTop project is to develop a variety of technologies, architectures and methods, including: a more flexible modular, open, RF System scalable RF architecture; software definition function, through software upgrades to quickly adapt to new threats or meet the new (Compared to traditional masts); lower cost (compared to conventional systems); in the mast (in the case of a mast), RF System a lower cost (compared to a conventional system) To optimize the deployment of more RF functions; in the antenna mast and platform architecture to achieve seamless compatibility between the integration.
