• Perform radar‑specific performance characterization, including:
  • Range/Doppler resolution and accuracy
  • EVM, BER, SNR, detection probability, false‑alarm rates
  • Phase noise, spurs, jitter, and clock coherence analysis
• Support DFx (DFT/DFM), manufacturing tests, field diagnostics, and operational calibration.
• Contribute to EMC/EMI compliance planning for radar and SDR systems.

• Produce and maintain clear, traceable design documentation, including:
  • Signal‑processing and waveform specifications
