Digital Pulse Compression Sub-System (DPCSS) Overview

Rakon's Digital Pulse Compression Sub-Systems (DPCSS) are the ideal solution when upgrading SAW-based radars. High speed digital processing enables remarkable increases in overall system performance. All pulse compression parameters are fully programmable.

Digital PCSS Selection

  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 customized to match linear or nonlinear chirps to generate compressed pulse. A pulse compression filter is customized 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:  SAW based pulse compression RADARS upgrade, FMCW RADARs.
