1 Introduction

Modern satellite radar systems demand both exceptional RF front-end chips and high-capability data processing platforms. The combination of TI's AWR2188 radar transceiver and NVIDIA's Jetson AGX Orin offers an optimal solution, providing:

  • High-resolution radar sensing – leveraging the AWR2188's 76–81GHz frequency modulated continuous wave (FMCW) capabilities
  • Robust long-range data transmission – enabled by FPD-Link IV SerDes technology

This document focuses on system integration aspects: radar configuration, SerDes setup, and Orin platform configuration, ensuring successful raw radar data capture via the V4L2 (Video4Linux2) interface on the Orin. Signal processing algorithms for point-cloud generation are outside the scope of this document.
