RF Demodulator and Processing – D00200-01A
This device, developed for radar applications, drives an RF demodulator and performs digital processing algorithms like equalization, decoding, radar processing, and direction finding. It includes:
- RF Demodulator D00200-01A: Input range of 400–4500 MHz, features direct baseband conversion with a local oscillator and two 16-bit ADCs.
- Processing Board D00200-02A: Equipped with an FPGA VIRTEX VI (XC5VFX30T) and Power PC Freescale communicator (MPC8349), with Gigabit fast connection for high-speed data handling.
Fast Recording System
The Fast Recording System (FRS) is a cutting-edge device for analog signal recording across 10–1000 MHz with a maximum sampling frequency of 2.2 GHz. Supporting up to 60 minutes of recording, it operates via manual control, trigger, or gate, like an oscilloscope, but offers extended acquisition depth for prolonged recording.
With an optional down-converter, signals over 1 GHz can be captured. The FRS is configurable to fit customer requirements, making it ideal for industries needing detailed asynchronous event analysis and inter-event relationship tracking.
Multichannel Acquisition System – D00210100
This system includes a proprietary sub-rack, CAS boards, and an AM control board, supporting up to 256 analog channels. CAS boards sample up to 16 analog channels at 144 kHz, with 24-bit ADC dynamics, powered by DSP (ADSP21469 SHARC) and FPGA (XC5VFX30T) for fast Gigabit Ethernet communication.
Electric Phase measurement unit for Laser Telemetry
Designed for laser telemetry applications, this unit offers frequency ranges from 5 to 230 MHz and high precision (0.001-degree phase resolution). Data is output via USB with rates of 10–1000 measurements per second.
ASU2 Antenna Emulator
The ASU2 antenna simulator replicates the behavior of a phased array antenna for modern fighter aircraft by generating analog RF signals similar to those produced by aircraft systems. We handled the entire design and system analysis, including Microwave subsystem specifications, real-time firmware for multiple FPGAs, and system management software. Additionally, we created dedicated hardware, including FPGA-based interface boards and fast attenuator drivers. Complete hardware and software documentation, such as user manuals, test plans, and validation support, were provided to assist the Customer Program Manager in managing critical points and project updates.
ASU2 Emulator
The ASU2 simulates a phased array antenna for modern fighter aircraft, focusing on interactions with optical fiber interfaces and the scenario generation system.
Developed in Dune, it replicates the antenna’s receiving section and manages four real-time Hot-Link channels at 600 Mbps per channel. Incoming data is processed via AlphaData boards with FPGA Xilinx Virtex IV.
The dedicated Man-Machine Interface (MMI) enables data acquisition, arrangement, display, and storage on magnetic devices per user specifications.
HF Modem for Avionic Communication
This system, developed on the Motorola DSP56309 platform, supports avionic HF communication applications in line with STANAG 4197 standards.
Implemented functions include Doppler correction, 4 DPSK modulation and demodulation, end-of-frame realignment, interleaving, and BCH coding/decoding for secure and reliable data transmission.
Torpedo Control System Simulator
This system emulates a torpedo control system to verify and control the complete logic of a torpedo head offline. DUNE designed the hardware and real-time software architecture for data processing, visualization (via an industrial SIEMENS terminal), and LAN-based graphic data exchange.
Architecturally, the system operates on a VME bus, with control managed by a Radstone PPC board (VxWorks OS). Additionally, two I/O boards are on the bus, while torpedo head interface functions are handled by custom-designed boards from DUNE.
