Building Radar and EW Research and Prototyping Testbeds

Radar and EW researchers and systems engineers must often spend significant time building testbed infrastructure rather than focusing on their algorithm. This wasted effort is an obstacle to moving new ideas quickly from whiteboard to hardware demonstrator to fielded system. They need flexibility to adapt to emerging requirements, scalability to multichannel architectures, artificial intelligence for cognitive capability, and open software to rapidly migrate IP from simulation to hardware, to:

 

  • Quickly realize a hardware testbed with minimal custom hardware and firmware development 
  • Synchronize multiple transmit and receive chains across an array and avoid bottlenecks in moving multichannel data from I/O to processors
  • Process signals inline to assess novel capability such as spectral interference avoidance, clutter suppression, and automatic target recognition
  • Implement machine learning algorithms that enable cognitive radars to adapt to new targets, countermeasures, and channel conditions

Open Architecture for Radar and EW Research

  • N320/N321 USRPs are networked software defined radios that allow sharing of local oscillators across units, providing phase coherency across an array. 
  • The USRP Hardware Driver™ (UHD) and RF Network on Chip (RFNoC™) support open-source development and simplify heterogeneous processing with FPGAs in SDR applications.
  • The OctoClock-G CDA-2990 module provides high-accuracy time and frequency reference distribution for multi-channel systems synchronized to a common timing source. 
  • Freely available application software is provided in C++ and built upon the RFNoC API in UHD 4.0, providing out-of-the-box streaming and synchronization functionality.
  • Reference architecture documentation is provided, accelerating the system-level getting started process for a multi-radio testbed.
