Radar Systems

DUNE has a deep skill in designing and developing hard real-time systems where flexible multi-processor architectures are needed to process high data rate and guarantee the system reliability and the failure run-time management.

Our company has developed the signal processing sections of several 2-D and multi-function 3-D radars equipped with active phased array antenna used at short and medium range for aerial discovery, research and tracking of targets in antiaircraft systems.

The entire project documentation, according to the ISO9001:2008 and NATO Standard AQAP-150, is integrated to the system delivery.

3D Multifunction Radar System (MFRA)

It is a multifunction radar operating at C-band, performing concurrently 3D detection, multiple target tracking and missile guidance. It is designed to be on board medium and large tonnage vessels having full volumetric search coverage, low altitude and surface search, multiple target tracking, up-link transmission.

DUNE has developed the Signal Processing section (Electronic Counter Counter Measures, Main Beam Cancellation, Sidelobe Cancellation, Sidelobe Blanking, Clutter Cancellation algorithms, Advanced anti Multi path techniques, fault tolerance and automatic reconfiguration) on a VXS rack including 2 Mercury RapidIO Switches and 7 Mercury PPC boards (HCD5220) including 4 processors each.

The real-time architecture has been designed, simulated, optimized and realized using a cluster of 26 processors operating with parallel, serial and round-robin scheduling supporting automatic architecture reconfiguration according to the incoming signal characteristics (duration, signal types, required processing, error presence).

Land Based and Shipborne 3D Radar System (KRONOS)

It is a 3D multi-role C-Band radar with a full solid state active phased array antenna used both in land based and shipborne configurations at medium range having an extended 3D coverage for search, tracking and auxiliary activities.

DUNE has realized a first version of the Signal Processing section in a cluster of DSPs and in the following it has managed and developed the system migration and porting on a multi-processor PPC architecture in order to prevent HW obsolescence and upgrade performances.

DSP version DUNE has developed the Signal Processing section (Digital Down Conversion, Digital Pulse Compression, Real Time Weight Selection, Moving Target Detection, Constant False Alarm Rate, OSGO/CAGO, thresholds application and Jammer filtering algorithms) on a rack including 2 Bittware TS6U boards (Tiger-6U-cPCI, Octal ADSP-TS101S Tiger SHARC 6U cPCI board) including 8 DSP (ADSP-TS101S Tiger SHARC) and Xilinx Virtex-II reconfigurable FPGA.

PPC version DUNE has developed the Signal Processing section (Main Beam Cancellation, Sidelobe Cancellation, Sidelobe Blanking, Clutter Cancellation algorithms, fault tolerance and automatic reconfiguration) on a VXS rack including 2 Mercury PPC boards (HCD5220) with 4 processors each.

The real-time architecture has been designed, simulated, optimized and realized using a cluster of 8 processors operating with parallel, serial and round-robin scheduling supporting automatic architecture reconfiguration according to the incoming signal characteristics (duration, signal types, required processing, error presence).

2-D Medium-Range Radar

It is a 2D medium-range air detection system designed for vessels.

DUNE has developed the digital processing architecture (digital compression, platform motion and sensitivity time control compensation, automatic frequency, gain and real-time weight selection, moving target detection, constant false alarm rate and clutter management) on a Bittware PCI board with 8 DSP Tiger Sharc.

The real-time architecture has been designed, simulated, optimized and realized using a cluster of 8 processors operating with parallel and scheduling.
