equipment. The series also has one or two configurable sensing zones and a beam pattern of 90° x 76°. Its dead zone measures 400 mm for moving objects and 1000 mm for stationary objects. A notable feature of the QT50R is its ability to be configured through DIP switches. This enables simple setup in the field. However, some applications call for more sophisticated configurations. For example, the Q130R sensor (Figure 5) is designed for applications requiring sophisticated detection
capabilities and advanced configuration options. It operates at 24 GHz, has a range of 40 m, a beam pattern of 90° x 76° or 24° x 50°, a dead zone of 1000 mm, and provides accurate detection of moving and stationary objects. Notably, the Q130R employs a PC-based graphical user interface (GUI) for complex setup and fine- tuning. For example, it can be used for positioning feedback in a busy rail yard. In this application, the sensor can be configured to ignore trains parked in the background on one track while recognizing other trains as they pass in front.
Conclusion
Radar sensors are uniquely capable of operating in a wide range of outdoor and harsh environments. To maximize the benefits of radar technology, it is essential to analyze the application requirements and select a sensor with the right operating frequency and beam pattern, among other specifications. With a well-chosen radar, many challenging remote sensing applications can be addressed.
