PARSAX An Informal Look at Radar Technology and Applications within TU Delft


Software Defined Radar

The ElectroScience Laboratory in Ohio State University recently announced their new development - 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 Software Defined Radar Architectureallow for maximum flexibility in algorithm design. Until this point their concept and development is very similar to our PARSAX radar. But if in the PARSAX radar the parallel coherent transmit and receive channels enable the exploration of simultaneous polarimetric information about radar objects, the multi-channel radar from Ohio has a few modes such as multiple-input multiple-output (MIMO) radar and polarimetric radar.  As for our group, the target phenomenology is one of research topics. Another area of study which will also be explored with SDR system is the urban propagation environment for radar.

The ESL 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
