What Is mmWave Radar?

The mmWave Band

Radio waves with wavelengths of 1-10 mm and frequencies of 30-300 GHz. Strong directivity and directionality allow focused radiation with minimal interference with other radio waves.

Radar Sensing Principle

Emits radio waves at a target and receives reflected waves to detect distance, angle, and velocity simultaneously from a single compact module.

Growing Fast

Advances in silicon CMOS and SiGe semiconductor processes are making mmWave modules more compact and affordable, driving rapid adoption across automotive, smart home, and healthcare markets.

Key Applications

Automotive Safety

Child Presence Detection (CPD) prevents heatstroke accidents by detecting children left in vehicles — even when hidden under blankets. Occupant monitoring tracks biometric indicators and driver alertness. Parking assistance systems leverage long-range, weather-resistant detection.

Smart Home & Security

Enable presence-aware lighting, air conditioning, and TVs that respond to occupant movement. Detect multiple people and fine gestures within a defined area. Provide privacy-preserving surveillance — no camera imaging required — that works reliably in the dark.

Healthcare Monitoring

Enable 24-hour, non-contact patient monitoring where camera installation raises privacy concerns. Detect falls and unexpected incidents by tracking full activity range. Measure heart rate and respiratory rate contactlessly using the high precision of mmWave micro-motion sensing.

Why Choose Murata mmWave Radar?

High Resolution

Extremely short wavelengths (1–10 mm) enable fine distance/position discrimination and simultaneous detection of multiple objects.

All-Weather

Radio waves propagate through rain, fog, smoke, and dust with minimal attenuation — reliable sensing where cameras and LiDAR fail.

Compact & Integrated

Short mmWave wavelengths enable miniaturized circuits and antennas, accelerated by advances in silicon CMOS and SiGe semiconductor processes.

Distance, Angle & Speed

FMCW detection simultaneously measures target distance, angle, and velocity from a single compact module.

Frequently Asked Questions

Murata offers modules in the 60 GHz band for consumer and industrial applications and the 77–79 GHz band for automotive applications. The higher frequency automotive band provides the range resolution needed for exterior vehicle sensing.

Yes. The high precision of mmWave radar allows detection of minute chest movements caused by breathing and heartbeat. This enables non-contact measurement of respiratory rate and heart rate — particularly valuable in healthcare environments where attaching sensors is impractical.

mmWave radar detects the presence, position, and motion of people without capturing any visual image. This makes it suitable for bedrooms, bathrooms, and medical facilities where camera installation would violate privacy.

No. mmWave radio waves propagate on a larger scale than fine particles such as rain, fog, and dust, so scattering and absorption effects are minimal. Unlike cameras and LiDAR, mmWave radar maintains stable performance in adverse weather conditions.

FMCW (Frequency Modulated Continuous Wave) uses a chirp signal to measure distance, angle, and speed simultaneously and is suitable for high-precision applications. The pulse method emits short bursts and measures time-of-flight; it has a simpler circuit but is more commonly used when high precision is not required.
