SDR2Lib -Software Defined Radar Receiver Library

Radar systems are using in varying fields from military to civilian applications. Software DefinedRadar (SDR) is the latest trend in radar development. In Software Defined Radar, most signal detectionand radar processing are performed by FPGA and/or DSP. Since the radar platform is completelysoftware defined, it can adaptively switch between different modes of operation for radar bymodifying both transmit waveforms and receive signal-processing tasks on the fly. Software definedsystem lends itself for broad range of radar applications as it allows to perform to update of radarparameters for various different applications.

C2Tech’s embedded team developed a SDR reciever library. Based on our comprehensive radarsignal processing library and RF capabilities this radar reciever system is an embedded design withall the flexibility and modularity of state-of-the art software component technology.

Architecture

The Software Radar (SR) architecture is customized to efficient implementation of all traditional radaralgorithms with maximum flexibility. SR architecture;

• means not only digital, but also programmable, reconfigurable and currently upgradeable
• reduces the content of analog components to a sufficient minimum and emphasizesprogrammable digital signal processing to enhance overall radar flexibility.

Great achievements in SR implementation became after appearance of high performance DSP andFPGA. C2Tech has capability to design hardware blocks including Analog, Digital (DSP, MCU, FPGA’sand etc.) and IF/RF design.
