Nanoradar SR75 4D sensor

Order the Nanoradar SR75 4D sensor - an all-seeing eye for your drone!

Nanoradar SR75 4D sensor is an advanced spatial awareness system for drones. It provides simultaneous detection of objects by range and angle. This sensor sees the world in three dimensions with added speed. Your drone will be able to autonomously navigate obstacles in challenging environments. It is a key component for intelligent autonomous flight and navigation.

This model uses millimeter radio waves to scan space. It works in all weather conditions and under different lighting conditions. The sensor forms a detailed picture of the environment in real time. Algorithms process the data to construct a movement trajectory. You will get a drone that sees and understands space like a living pilot.

• 4D scanning of space (range, azimuth, elevation, speed).

• Working in difficult weather conditions (rain, fog, dust).

• Wide viewing angle and long range object detection.

• High data update rate for dynamic flight.

• Compact design and low power consumption for integration onto a drone.

How does this 4D radar system work?

The sensor emits short radio wave pulses in the millimeter range. They are reflected from surrounding objects and come back. The receiver picks up the reflected signals and analyzes them. The system calculates the distance to the object, its angle and radial speed. This creates a rich, four-dimensional view of the surrounding space.

The key difference from lidars is their independence from lighting and weather. Radio waves travel through rain, snow, dust and fog. This makes the system reliable for commercial missions in any environment. It can detect non-metallic objects that are difficult for other sensors to detect. For example, wires, tree branches or chain-link fences.

The technical specifications of the SR75 4D are impressive. The detection range is up to several tens of meters. The azimuth viewing angle reaches 120 degrees. The elevation angle is also wide for full coverage of the space. The frame refresh rate is tens of hertz for smooth navigation. Centimeter-level distance measurement accuracy.

The functionality includes simultaneous tracking of multiple targets. The system measures not only the position, but also the speed of objects. Data is output in point cloud or processed object format. UART, CAN, Ethernet communication interfaces are supported for integration. Powered by the drone's on-board network, power consumption is about 5 W.

Features and device

The design of the device is made in a protected housing. It protects sensitive electronics from vibrations and shocks. The antenna system is built-in and does not require external protruding elements. Light weight and dimensions allow the sensor to be installed on different drones. The housing promotes efficient cooling during operation.

The sensor is compatible with popular autonomous driving platforms. It can integrate with ROS (Robot Operating System) and PX4/ArduPilot autopilots. This allows the construction of localization and navigation maps (SLAM). The drone will be able to independently build a route in an unfamiliar area. It is also possible to work in following mode.

The system opens up new possibilities for autonomous drones. It is ideal for industrial and infrastructure inspections. Search and rescue operations require reliable vision in challenging environments. Delivery of goods in an urban environment requires reliable avoidance of obstacles. Any mission where complete autonomy and safety are important.

Proper integration is essential for effective operation. The sensor must be installed with a good view in the direction of travel. Calibration and tuning of data processing algorithms is critical. AEGISKY specialists are ready to provide consultations on integration. This will help unlock the full potential of the system on your device.
