ELSYS ELT2 Radar Module
Features
The ELSYS Radar module is a peripheral for the Elsys ELT2 sensor to enable distance measurement using radar technology. The radar module sits under the lid with no protruding parts, making the ELT with the radar module discrete and easy to install.
Use cases
- Distance measurement
- Level measurement
- Smart parking
Theory of operation
The radar module employs pulse-coherent radar technology to measure the distance to the nearest target by emitting a high-frequency pulse and analyzing the returned signal. It offers selectable distance-measuring algorithms, allowing adaptation across various applications. The module includes an internal lens to achieve a narrow detection range, and the reported distance is calibrated to reflect the distance from the top of the module lid to the target.
Technical Specifications
| Parameter | Min | Max | Unit |
| Operating temperature | -40 | 60 | °C |
| Operating frequency range | 57 | 64 | GHz |
| Distance accuracy (@25 °C) | 2.67 | 2.83 | mm |
| Distance resolution (@25 °C) | 1.2 | 2.4 | mm |

Installation
Insert the radar module connector into the terminal block of the ELT. To enable the radar, set the ELT external configuration to “Radar”. Use the Sensor Settings app and NFC to configure the radar.
Note: Take care when handling the delicate flex cable.
Radar Settings
| Setting | Explanation |
| Range start | Near distance for the measurement range. |
| Range stop | Far distance for the measurement range. |
| Reference shape |
Note: Using “Generic” will increase power consumption about four times compared to “Planar”. |
| Peak sorting algorithm |
|
| Median Filter |
Note: Turning median filter on increases the power consumption approximately 3-5 times. |
- If the expected measuring interval is known, it is recommended to set the range start and stop values to only cover that specific range. This minimizes power consumption and maximizes accuracy. Accuracy up to one meter is generally ±1 mm, ±5 mm up to 8 meters and ±10 mm above 8 meters.
- Measurements are inherently temperature compensated by means of each measurement being preceded by a short calibration radar pulse every sampling.
Error messages
In case of communication or data errors, the sensor will report error codes using the debug handle (see ELSYS Uplink Payload Description).
| Value | Error |
| 0x01 | No communication with module |
| 0x02 | Invalid range |
| 0x03 | Config not written |
| 0x04 | Invalid configuration, check range |
| 0x05 | Protocol error |
| 0x06 | No target detected in range |
