Elettronica’s Nettuno naval ECM solution
Elettronica’s electronic warfare portfolio is based on the firm’s strengths in key areas such as phased array antennas, Digital Radio Frequency Memory (DRFM), solid state Rx/ Tx modules, and digital receivers. The Nettuno-4100 naval ECM system is intended to provide naval platforms with an active electronic defence using selected ECM tactics, exploited through DRFM generated signals. The system can be equally effective against both missile attacks in the terminal phase and hostile long range designation radar systems, surface search and tracking radars.
The Nettuno- 4100 has a scalable architecture, which can be configured for different needs by assessing the needed Effective Radiated Power (ERP) in relation to the host ship’s Radar Cross Section (RCS) and role, and by dimensioning the antenna array and the transmitted power to the ERP required for the defence purposes. In addition, Nettuno 4100 systems can operate in conjunction with other onboard EW sensors and emitters.
The system has full azimuth coverage and can steer through 50° in elevation, and features electronic beam steering, including electronic stabilisation to counter ship movements. Of particular importance is a single Nettuno installation’s ability to jam multiple threats through time-sharing resource management. It covers the H to J band frequencies and its solid-state design ensures both high ERP and graceful degradation in case of minor failures. The design also removes the need for system warm-up times, and is inherently more reliable and maintainable than legacy systems, with Built-In Test Equipment (BITE) down to the module/card level. The solid state architecture also makes for relatively simple shipboard integration and installation, as no microwave guides are required.
The Nettuno-4100 system is designed for ease of maintenance and support, and a host of products and services are readily available to minimise downtime. These include field test equipment, ground support equipment, automatic test equipment, library programming, and library loading/ unloading. Nettuno family systems are installed in a range of operational warships, including the Italian STOVL carrier Cavour and the multinational Horizon and FREMM frigates.
