- _ _ Digital pulse compression module To make an enquiry please email: [email protected] CI F04 and CI F05 are digital pulse compressors that perform matched filtering of a radar return signal. CI F04 is a stand alone single channel compressor with IF analog I/Os while CI F05 is a dual channel compressor with IF analog I/Os. Both products may be customized to match linear or non linear chirps to generate compressed pulse. CI F0x may be used as a replacement of existing SAW based pulse compressor to overcome device obsolescence or enhance RADAR performances. CI F0x compressor behavior and performances are reproducible from one unit to the other. No matching is needed. Rakon-Temex will customize pulse compression filter according to the characteristics requested by the customer (Chirp duration, bandwidth, compressed pulse width, chirp slope ...). The compressor unit is provided with FPGA firmware loaded, including pulse compression filter. Digital pulse compression unit CI F04 : One compressor channel with IF analog I/Os CI F05 : Two independent compressor channels with IF analog I/Os 2 selectable waveforms for each channel High precision clock BITE function High BxT compression gain • SAW based pulse compression RADARS upgrade Note: In this entire document, CI F0x stands for CI F04 or CI F05 Oct 16th, 2015 CI F04 / CI F05 Compressor Revision A4
