rakon Digital pulse cumpicssiuM muuuic CI F06 Expander and Compressor To make an enquiry please email: [email protected] Product description CI F06 unit includes a digital pulse expander and the matched digital pulse compressor housed in a single unit. The pulse expander generates a frequency coded pulse, also called a chirp. Pulse output is IF analog. The pulse compressor performs matched filtering of the expanded chirp. Compressor pulse input and output are IF analog. CI F06 may be customized to generate and match linear or non linear chirps. CI F06 may be used as a replacement of existing SAW based pulse expander and/or compressor to overcome device obsolescence or enhance RADAR performances. CI F06 behavior and performances are reproducible from one unit to the other. No matching is needed. CI F06 may be used with CI F04/05 to get multiple compressor channels, also without matching required from one unit to the other. Rakon will customize pulse expander chirp and pulse compression filter according to the characteristics requested by the customer (Chirp duration, bandwidth, compressed pulse width, chirp slope ...). The unit is provided with FPGA firmware loaded, including pulse expander waveforms and pulse compression filter.

FPGA WFMSel_E Wavefo rm selection ^ Trigger Stored Timing Wa veforms Out_E Fig. 1 : CI F06 functional block diagram Unit description. The internal low noise system clock is locked on an external clock (derived from the RADAR system clock). For proper operation, the clock should be a good quality clock, with a low phase noise close to the carrier. CI F06 unit is provided with FPGA firmware loaded. Functions, and channels specifications (time dispersion, compressed pulse width,...

rakon L/igital CI F06 Expander and Compressor Pulse compressor channel description. Input chirps are filtered (anti-aliasing filter), sampled and down-converted to baseband. I and Q baseband data are processed by FIR filters whose coefficients are matched with the expander chirp characteristics. Digital baseband I/Q compressed pulse is then up-converted to carrier frequency and converted into analog signal. As inputs and outputs are IF analog signals, CI F06 is well suited to upgrade SAW based pulse compression Radars. For better compatibility with old SAW based subsystems, an adjustable additional...
