Warning

Motion BVH Must Be Enabled for RTX Radar

RTX Radar requires Motion BVH to be enabled for the Doppler effect—and therefore RTX Radar entirely—to be modeled correctly. Without Motion BVH enabled, Isaac Sim will not create RTX Radar assets.

Motion BVH is disabled by default in Isaac Sim for performance reasons. You must explicitly enable it before using RTX Radar.

To enable Motion BVH, add the following command line arguments when launching Isaac Sim:

--/renderer/raytracingMotion/enabled=true \
--/renderer/raytracingMotion/enableHydraEngineMasking=true \
--/renderer/raytracingMotion/enabledForHydraEngines='0,1,2,3,4'

Or in standalone Python, pass enable_motion_bvh=True to the SimulationApp constructor.

Refer to How to Enable Motion BVH for complete instructions.

IWRL6432AOP

Texas Instruments IWRL6432AOP is a single-chip, low-power industrial mmWave radar sensor operating in the 57 GHz to 63.5 GHz band with an integrated Antenna-On-Package (AOP). Built on TI’s 45nm RF CMOS process, the device combines an FMCW transceiver, ARM Cortex-M4F application processor, hardware accelerator, and on-package antennas into an extremely compact form factor. It is designed for applications such as building and factory automation, commercial and residential security, presence and motion detection, and gesture recognition for human-machine interfaces.

Key Features

• Antenna-On-Package (AOP): Integrates 2 TX and 3 RX antennas directly on-package, significantly simplifying PCB design and reducing BOM cost.

• Ultra-accurate chirp engine: Fractional-N PLL-based FMCW chirp generation for precise ranging.

• Multiple low-power modes: Idle mode, sleep mode, and deep sleep mode with clock gating and selective IP power-down; application image and RF profiles can be retained across low-power transitions.

• Power flexibility: Supports BOM-Optimized and Power-Optimized power rail configurations; compatible with the TPS628502-Q1 power supply solution.

• Built-in self-calibration: On-chip calibration system with ROM-based firmware requires no external calibration hardware.

• Edge AI ready: Supported by TI Edge AI Studio for on-device model training and deployment (surface classification, point cloud classification, and more).

• Radar Data Interface (RDIF): Enables raw ADC sample capture for external signal processing development.
