    To get a strong signal, align the radar sensor as far as possible at a right angle to the target object. 2. Smooth surfaces act as mirror: The smoother the surface, the more important the correct alignment of the radar sensor. ondosense.com Document version: 1.1...

  • Page 7 Figure 1.3: A smaller aperture angle leads to a smaller measuring spot size. The radar signal is focused on the measuring target (green cube) and not spread on the background (orange area). The measurement is therefore more focused and the signal strength received by the radar sensor and the measurement accuracy will be high. ondosense.com Document version: 1.1...

  • Page 9 Figure 1.5: In the upper picture the signal strength is relatively low, without a radar reflector. In the lower image, the signal strengh is significanlty improved by installing a radar reflector on the measurement target - in this case a crane. ondosense.com Document version: 1.1...

  • Page 10: Radar Measurement Properties

    Only a limited amount of the radar signal is reflected, so that the radar sensor detects the distance to the object behind it with high accuracy. Table 1.1 gives an overview of the ability of radar to penetrate different materials. ondosense.com Document version: 1.1...
  • Page 11 Key messages: 1. Radar allows you to measure through non-conductive materials: While water drops and high humidity do not have a big impact the radar signal, continuous water films are more or less impossible to penetrate. ondosense.com Document version: 1.1...

  • Page 12: Radar Resolution

    Pay attention to how many objects your measuring spot covers and which objects are relevant for your distance measurement. If the radar distance sensor cannot detect two or more target objects separately and thus resolve them, then the distance to neither object can be reliably determined. ondosense.com Document version: 1.1...

  • Page 13: Averaging Across The Measuring Spot

    If the surface curve of the measuring object is known, the measured distance can be corrected to detect the exact distance value. This is the case with round objects or surfaces, for example. If necessary, OndoSense provides support in the development of a radar algorithm for correct distance calculation.

    These 4 pins are needed for operating the sensor with RS485 communication. The sensor can be connected with an 8-pin a-coded M12 cable. Additional pins are the 3 switching outputs and the current loop. Figure 2.1: Pin-out of the sensor. ondosense.com Document version: 1.1...

  • Page 15: Setup

    Setup Setup In normal operation, the OndoSense sensor works fully automatically as stand-alone device. The Configuration Box and the configuration software OndoNet described in this chapter, are only required for the initial setup of the sensor settings for the specific application. Once the configuration is completed, the sensor can be discon- nected from the Configuration Box and used as stand-alone device.
