Abstract

This document was translated from a simplified Chinese source. (ZHCAG83)

MmWave imaging radar is a core technology in fields such as Advanced Driver Assistance Systems (ADAS), autonomous driving, and industrial automation. Compared with traditional radar, imaging radar utilizes multi-channel antenna arrays to achieve higher angular resolution and can generate high-precision point clouds, thereby more accurately identifying and classifying objects. The high-performance single-chip mmWave radar AWR2188 introduced by Texas Instruments (TI) operates in the 76–81GHz frequency band, integrates 8 transmit and 8 receive channels, and has a built-in complete radio frequency (RF) front end, phase-locked loop (PLL), and analog-to-digital converter (ADC), achieving high integration and compact packaging. This article will introduce the boot process of the AWR2188 chip in detail. We will walk through the process from hardware power-on to firmware loading, aiming to provide developers with a clear and complete operation guide, helping them quickly get started with AWR2188 system development, and accelerating the deployment of imaging radar applications.
