USRP based cognitive radar testbed

Cognitive radar is a relatively new field of research and the existence of low cost experimental testbeds is limited. This work will show the development of a low cost experimental testbed for experimental validation of cognitive radar algorithms. The testbed is based on USRP's, which is a low cost software defined radio developed by Ettus. Both the hardware and the software have been developed to provide a complete system for experimental validation of cognitive radar. Results will be presented that show the PRF of the test bed being adapted in response to the velocity of a non-cooperative target.
