What does it actually take to build a real-time, high-resolution impulse radar with a USRP X310?
I spent months getting a USRP X310 to reliably stream data at 200 MS/s for a real-time impulse radar. Along the way, we encountered many practical hardware and software challenges that are easy to overlook when designing an SDR-based radar system. I’m sharing what we learned because I hope it can save other researchers some of the time and trial-and-error we went through.
We recently published a detailed, step-by-step implementation documenting what we learned as an open-source paper available on: High-Resolution Real-Time Impulse Radar Using Software-Defined Radio: A Step-by-Step Implementation with USRP X310. The paper goes beyond the radar concept and focuses on the practical implementation details required to make the system work reliably, including:
• High-rate data streaming at 200 MS/s
• 10-Gigabit Ethernet configuration and data transfer
• Hardware/software optimization for sustained high data rates
• Timing and scan-to-scan synchronization
• Measurement of timing misalignment and temporal alignment
• Experimental validation of 5-ns transmission pulse
The goal of this work is not only to demonstrate that an X310 can be used for radar, but to provide the practical implementation details that researchers often need when attempting to reproduce or extend an SDR-based radar system.
If you're working with USRPs for radar, I'd be very interested to hear about your experiences—especially challenges you've encountered with high-rate streaming, synchronization, or real-time processing.
