USRP Radar

This is a C++ program for transmit/receive, processing, display and storing radar data using a USRP software defined radio. It has the following dependencies:

• UHD library
• QT
• QWT
• Boost
• GNU libgomp
• OpenCV
• CUDA

It has been compiled on a Ubuntu Linux 16.04 LTS platform, but has earlier been compiled on both linux and windows platforms. It has been tested with the following USRP configuration:

• Ettus X310
• UBX-160/SBX-120 in port RF0
• TwinRX in port RF1
• 2x10GB ethernet connection

One way to compile the program is to open the .pro file in QT Creator and compile through this. The CUDA files is compiled and linked to the program.

RF frontend consists of an amplifier on transmit, and LNA's on receive, combined with filters on transmit and receive. Antenna rig consists of one transmit antenna and two receive antennas in an array. Program uses phase monopulse technique to measure angle of arrival.
