AbstractIAI proposes to develop a reconfigurable L-band radar transceiver module. The emphasis will be to implement most of critical radar functionalities like: ýý Baseband modulation signals ýý Orthogonal high frequency pseudo random codes for pulse compression ýý Direct Digital synthesis (DDS) or numerically controlled oscillators (NCO) for generating RF carrier reference signal ýý DDS driven Frequency sweep for FMCW (Frequency Modulated Continuous Wave) radar functionality ýý Sigma-Delta technique to direct carrier synthesis ýý Received signal processing to generate I/ Q components on a single embedded platform. Such a platform will be a combination of high speed DSP and FPGA on one board. This will considerably reduce the component count and form factor for a radar transceiver design. By simply programming an FPGA with a different "bitstream" file, we can control the radar functionality as pulse modulated or frequency modulated. This work will be synergistic with ongoing efforts at IAI, which involves L-band radar design. Advantages of such a system are: ● Reconfigurable radar transceiver, not just in operational bandwidth/ carrier, but also in modulation (pulsed/ frequency swept) ● Low form factor ● Low power consumption
