Ultrasonics. As the name ultrasonics implies, this term deals with that branch of acoustics whose frequency waves are above the highest frequencies audible to the human ear.

Radar (short for "Radio Detection and Ranging"), based on the principle of sending very long wavelength radiation (called microwaves) from an antenna, and then detecting that energy after it bounces off a remote target.

Radar object detection devices are typically classified in two classes, Doppler and Pulsed Radar. The main difference between these two is that Doppler systems require relative motion to provide an indication of an object being detected. Pulsed radar on the other hand can detect both moving and stationary, inanimate and animate objects. This is one of the technologies key benefits. Radar systems are also well suited for on-road and off-road applications, as these systems are not affected by environmental conditions such as mud, dirt, snow, rain, sunlight, or wind.
