Acconeer’s A111 – Pulsed Coherent Radar

Acconeer’s A111 radar sensor is based on a unique patented technology enabling mm accuracy with very low power consumption.

The Acconeer A111 is a low power, high precision 60 GHz pulsed SRD radar sensor with a footprint of 29 mm², delivered in one chip system in package (SiP) solution with embedded RF and antenna. The small size and the low power consumption makes it suitable for integration into any mobile or portable battery driven device.

The A111 radar sensor is based on a unique patented technology enabling mm accuracy with very low power consumption. The 60 GHz unlicensed ISM band provides robustness not compromised by any natural source of interference such as noise, dust, color, direct or indirect light, and easy integration with no need of an aperture. The A111 radar sensor detects multiple objects at close range with single measurements as well as continuous sweeps set to any frequency rate up to 1500 Hz. Additionally, the unique characteristics of the radar sensor enables material recognition and motion detection for advanced sensing applications.

Features

• mm Accuracy – distance mm accuracy for one or multiple objects
• Movement and speed measurement – continuous measurements up to 1500 Hz
• Material identification – distinguish between materials with different di-electric constant
• Microwatt – enables integration into any battery driven device
• Optimized integration – small one chip solution with embedded RF and antenna solution that requires no need for aperture
• Robustness – not compromised by any natural source of interference such as noise, dust, color, direct or indirect light

Applications

• Range measurements with high accuracy
• Configurable measuring update frequency, up to 1500 Hz
• Material identification. Possible to distinguish between different materials
• Movement, speed measurement and object tracking e.g. gesture control, vital signs
• Radar assisted camera for high performing lateral measurement i.e. Depth mapping, computational photography, assisted AF
• Proximity sensing with high accuracy. Possibility to define multiple proximity zones
• Radar assisted biometrics for enhanced security e.g. face recognition, human fingerprint recognition
