The Acconeer radar sensor is based on PCR (Pulsed Coherent Radar) technology. This technology offers several great advantages, including high range resolution with a power consumption of less than 1 milliwatt, which offers unique possibilities for integration into a wide range of devices. PCR is a patented proprietary technology; the result of more than 10 years of research by the nanoelectronics group at Lund University, targeted at the development of a methodology for high-accuracy distance measurement with ultra-low power consumption. The invention has already been proven in several steps and with different test configurations. It is recognized as a breakthrough in radar sensor technology.
Accuracy – The sensor records distance, speed and motion with millimeter accuracy.
Movement recognition – The sensor performs continuous measurements at up to 1500 Hz.
Material identification - The sensor can distinguish between materials with different dielectric constants.
Energy efficiency – Can be integrated into any battery-driven device due to power consumption in the microwatt range.
Robustness – The radar technology is extremely robust and is not affected by ambient light, noise or polluted environments.
Acconeer’s groundbreaking PCR technology significantly expands the opportunities for radar integration and brings the scope of possible applications to a whole new level. Many operational fields, such as human-machine interaction and advanced computer vision for battery-driven devices will be able to take great advantage of this new technology.
Acconeer’s radar is the first product to combine the low power consumption of a pulsed radar with the high accuracy of a FMCW system, all integrated into a single component. The technology enables generation of short and exact radar pulses and allows for the measurement of echoes in picosecond time resolution. Using the unlicensed 60 GHz band allows for a very small antenna and ultra-short pulses, creating a duty cycle of less than 1 per-mille. The result is a completely unique product.
Acconeer’s radar sensors perform ranging and level gauging with millimeter accuracy.
Low current consumption
The radar sensor’s update rate is programmable to allow performance to be optimized for the intended use case. For low-power application, such as a sensor in an IoT network, it can be configured to generate new radar data at low frequencies which results in low current dissipation. Sub-milliwatt power consumption can be achieved when running the radar sensor at 10 Hz while still maintaining millimeter accuracy.
Motion and gestures
The radar sensor can detect multiple objects and track the velocity of each object. This enables the development of applications based on an object’s motion. Applications include gesture control of smart devices and healthcare applications used to monitor pulse and breathing rate.
The data from the radar sensor contains considerably more information than simply range and velocity. By analyzing the data from the radar sensor, it is possible to actually categorize materials.
Easy to integrate
Acconeer’s radar sensor can be integrated within the physical casing of a product since the radio signal can propagate through plastic and glass. This offers a large degree of freedom when designing the end product. In addition, since the radar sensor operates on a distinct wavelength from most other electromechanical devices, the risk of signal interference is minimal and the sensor is unaffected by sound and light conditions. Since the antennas are integrated inside of the package, the sensor can be mounted on ordinary PCBs which reduces the design time and material cost for the customer.
