Rad-R: A Real-World Raw-ADC Dataset and Benchmark for mmWave Radar Robustness

Webpage | Code | Paper | PyPI

This is a demo release with 20 clips. The full dataset (~5,000 clips) will be available upon paper acceptance at NeurIPS 2026 Evaluations & Datasets Track.

Overview

Rad-R is the first mmWave radar dataset combining:

• Raw ADC captures from a TI MMWCAS-RF-EVM 77 GHz cascaded radar (12 TX × 16 Rx = 192 virtual channels)
• Controlled hardware fault annotations across 6 fault types at 3 severity levels
• Synchronized companion sensors: IMU (BNO055), temperature (DS18B20), GPS (NEO-M9N), camera
• 4 out-of-distribution evaluation splits: device, day, scene, severity
• RadRBench: standardized benchmarking system with 5 evaluation tasks

Fault Taxonomy

Fault Type	S0 (Healthy)	S1 (Mild)	S2 (Moderate)	S3 (Severe)
healthy	✓ baseline	—	—	—
vibration	—	<2 m/s² RMS	2-5 m/s²	>5 m/s²
misalignment	—	2-4° yaw	5-8°	>9°
blockage	—	<30% coverage	30-70%	>70%
rx_degradation	—	<3 dB drop	3-8 dB	>8 dB
thermal_stress	—	ΔT 5-10°C	10-20°C	>20°C
rf_interference	—	Far/off-axis	Partial align	Near boresight

Data Format

Metadata (viewable above)

Each row in the dataset viewer shows per-clip metadata including fault type, severity, sensor readings (IMU, temperature, GPS), device ID, and scene ID.

HDF5 Files (downloadable)

Each clip in the HDF5 files contains:

Field	Shape	Type	Description
iq	(1, 64, 256, 16)	complex64	Raw IQ tensor (frames, chirps, samples, rx)
rd	(224, 224)	float32	Range-Doppler map (log-normalized)
ra	(224, 224)	float32	Range-Azimuth map (beamformed)
microdoppler	(224, 224)	float32	Micro-Doppler spectrogram

Plus per-clip attributes: fault_type, severity, device_id, scene_id, session_id, run_id, sha256, and all sensor context values.

Quick Start

Option 1: radr Python package

pip install radr

from radr import RadRDataset, RadRBench, build_model

# Load dataset
ds = RadRDataset("path/to/data", representation="rd")
sample = ds[0]  # {"input": (1, 224, 224), "fault_label": int, "severity_label": int}

# Build and benchmark a model
model = build_model("resnet18")
results = RadRBench.evaluate(model, "path/to/data", representation="rd")
RadRBench.print_summary(results)

Option 2: HuggingFace datasets

from datasets import load_dataset
ds = load_dataset("gtaxcenter/radr", split="train")
