Radar Target Emulation Applications Overview
R2026bThe Radar Target Emulation on NI USRP Radio example guides you through a step-by-step workflow to generate and deploy a radar target emulation algorithm on the FPGA of an NI™ USRP™ radio. The example uses an HDL-compatible radar target emulator model from the Radar Target Emulator with HDL Coder (Radar Toolbox) example.
The following examples exercise the deployed design in different deployment scenarios:
| Example | Deployment Test Scenario |
|---|---|
| Pulse Radar Scenario Using Target Emulator on NI USRP Radio | Run a pulse radar scenario on an NI USRP radio with the target emulation algorithm deployed on the FPGA. Use the same radio to transmit a linear FM radar pulse train, then capture and plot the emulated target range-Doppler response in MATLAB. |
| Real Time Target Emulation on NI USRP Radio | Run a pulse radar scenario on an NI USRP radio with the target emulation algorithm deployed on the FPGA, running continuously. Use a second NI USRP radio to transmit a linear FM radar pulse train, then capture and plot the emulated target range-Doppler response in MATLAB. |
| Integrated Sensing and Communication Using 6G Waveform on NI USRP Radio | Generate a 6G waveform to track a moving object in an integrated sensing and communications (ISAC) scenario. Use the same radio to transmit the generated waveform, then capture and plot the emulated target range-Doppler response in MATLAB. |
Pulse Detection and Repetition
The Pulse Detection and Repetition on NI USRP Radio example uses a 4-target version of the target emulation design and extends the capability by adding an energy detection stage. This design enables you to detect unknown pulses in real time and characterize them on the FPGA, then respond by retransmitting emulated target responses.
The energy detector monitors the received signal, identifies pulse boundaries, and streams pulse metadata to the host computer for analysis or logging. The target emulator retransmits modified pulses. At run time, you can calibrate and control the deployed design from MATLAB®.
