Software Defined Radio and Radar

We are currently developing a software defined radar (SDR) platform that can adaptively switch between different modes of operation by modifying both transmit waveforms and receive signal-processing tasks on the fly.  High-speed analog-to-digital and digital-to-analog converters along with modern FPGAs and fast digital signal processors allow for maximum flexibility in algorithm design.  Additionally, parallel coherent transmit and receive channels enable the exploration of multi-channel radar modes such as multiple-input multiple-output (MIMO) radar and polarimetric radar.  Target phenomenology and the urban propagation environment for radar are two key areas of study which will also be explored with this system.

Software defined radar features:

  • 500 MHz or greater waveform bandwidth
  • RF Frontend tunable from 1-18 GHz
  • High-speed Xilinx FPGAs and Texas Instruments 32-bit DSPs for implementing real-time signal processing
  • Information driven active sensing layer based on a game theoretic approach to sensor management implements competitive sensor tasking to control the selection of the current radar operating mode
