If you want to play with radar — and who could blame you — you can pretty easily get your hands on something like the automotive radar sensors used for collision avoidance and lane detection ...

Ultrasonics or ultrasound is a radar-like system that uses ultrasonic signals at frequencies above those typical for human hearing, usually above 16 to 20 kHz. The 40- to 70-kHz range tends to be ...

In contrast, Sonair’s patented ADAR (acoustic detection and ranging) technology detects people and objects in 3D. A single ADAR sensor provides a full 180 x 180 field of view (FoV), and a 5 ...

The options when specifying sensors for long-range object detection or positioning usually boil down to two alternatives: optical sensors using either infrared or visible-red light and ultrasonic ...

The 12 ultrasonic sensors per car Tesla thinks it no longer needs, for example, are designed for close-range detection of other cars or objects; often thought of as "parking sensors," on Teslas ...
