System Solutions Overview

Capabilities

► SPECIFICATION DEFINITION:  Rakon offers solutions to retrofit or upgrade existing radar and Electronic Warfare (EW) systems, allowing improvements in overall system performance and extending the life of the equipment. Rakon has a strong heritage in radar subsystems, which started in the early 70s with the delivery of the first SAW (Surface Acoustic Wave) pulse compressors. Rakon now offers digital expanders and compressors, fully digital pulse compression subsystems, frequency synthesizers and complete modules (e.g. Local Oscillators, Coherent Oscillators). The company combines synthesiser and low noise oscillator technology through its strong capabilities in the domains outlined below.

► CAPABILITIES IN SUBSYSTEMS:  Rakon capabilities include all the retrofit project phases, from the specification definition and subsystem design through to final product delivery.

Capability	Image	Features
Specification definition .		• Feasibility study of specific system requirements and customer support on specification definitions. • Guaranteed fit, form and function compatibility with existing systems. • Measurement at customer site for specific parameters.
Subsystem design .		• Electronic design: from baseband up to 18 GHz, including digital (FPGA, communication interfaces), analogue (high speed ADC/DAC, high efficiency power supply management) and RF (filtering, low noise amplification, up/down conversion, PLL) functions. Expertise in design of complex mixed-signal multilayer circuits. • Digital signal processing: embedded software for radar applications, I/Q demodulation, phase detection, frequency synthesis, waveform generation, pulse compression, digital filtering. Expertise on latest Xilinx FPGA platforms (Ultrascale+, Zynq). • Mechanical design: complete 3D CAD modelling, form factor & interfaces definition, thermal and mechanical simulation.
Testing and validation .		• Specification validation. • Electrical & environmental testing. • Shocks & vibrations testing. • EMI/EMC. • Integration support.
Delivery of the final product and industrialisation .		• Engineering design following IPC standards. • Design robustness analysis (simulations, Monte-Carlo analysis, MTBF calculation). • Product Life-cycle Management with full definition and traceability (Bill of Material, drawings, manufacturing flowcharts, firmware).

Subsystems

►  PROFILE:  CIF0x series may be used as a replacement of existing SAW based pulse expander and/or compressor to overcome device obsolescence or enhance RADAR performance. CIF0x class compressor behaviour and performance are reproducible from one unit to the other. No matching is needed. CIF0x series products can also be customised to match linear or non-linear chirps to generate compressed pulse. A pulse compression filter is customised according to the characteristics requested by the customer (Chirp duration, bandwidth, compressed pulse width, chirp slope etc.). The expander and compressor modules are provided with FPGA firmware loaded, including waveforms and pulse compression filters.

♦ CIF07 is a digital dual channel expander with IF analog I/O.
♦ CIF06 includes a digital expander and a digital compressor with IF analog I/O in a single unit.
♦ CIF05 is a digital dual channel compressor with IF analog I/O, and performance matched filtering of a radar return signal.
♦ CIF04 is a stand-alone digital single channel compressor with IF analog I/O, and performance matched filtering of a radar return signal.
♦ CIE03 is a digital dual pulse compression module, well suited for RADAR performance enhancement.

CIE03 is also provided with FPGA firmware configured according to customer requirements. Analog inputs and outputs make it an ideal replacement for SAW based pulse compression subsystems. Each of the two available channels may be configured as chirp expander or chirp compressor. All the pulse compression parameters are programmable (centre frequency, bandwidth, time dispersion, modulation law, weighting function, etc.).

►  APPLICATIONS:  Retrofit or upgrade of civil air traffic control and military surveillance radars.

Synthesizer

►  PROFILE: The DS (Digital Synthesizer) series is a versatile FPGA-based low noise frequency synthesizer which can go up to the Ku-band. It can be combined with our low noise oscillators (OCSO or OCXO) to generate Local Oscillator (LO) signals for up- and down- conversion of RF signals. The waveform generator is highly flexible and programmable (standard interface: USB or SPI; BPX upon request) with several modes possible (CW, chirp, list, pulse, burst). This synthesizer synchronizes with the other synthesizers. It can be provided with internal or external clock reference.

►  APPLICATIONS:  Instrumentation, RADARs and Electronic Warfare Systems.
