Range Reporting Radar Sensor

Description

The FMCW (frequency modulated constant wave) radar sensor, OPS241-B, is capable of providing range reports for multiple objects in its field of view, detecting objects from 1 to 20 m away with a range resolution as small as 7.5cm.

 

The sensor is a complete single board radar sensor. It can report people at up to 8 m, cars at 15 m, and buildings or the ground as far as 20 m away. It communicates the range data over either a USB or UART interface. Designed as an Arduino shield board, it can be easily plugged into an Arduino or connected to a Raspberry Pi to quickly report range information. Multiple targets are reported over its 78-deg. wide field of view.

 

Applications for the OPS241-B include robotics, drones, and traffic monitoring systems. Drones can use the sensor for either collision avoidance or soft landings. In robotic applications, the OPS241-B can help robots detect and avoid obstacles. Adding a layer of application code and the OPS241-B can be used to count people or cars as they move through its field of view.
