While it’s not radar, subbing in ultrasonic ... detection project, with some slight modifications to tap into the received audio signal rather than just using the digital output of the sensor.

By measuring the amount of time that it takes for this send-and-receive process to occur, an object’s distance from the sensor can be calculated. Ultrasonic sensors offer several benefits, including ...

A DGIST team developed PINMAP, a cost-effective algorithm enabling low-cost LiDAR sensors to detect glass obstacles, ...
