Radar was initially developed in the early 1900’s as a technique to measure distance, direction, and speed of objects by transmitting pulses of high-frequency electromagnetic waves. These electromagnetic waves reflect off the object and back to its source. The time it takes the electromagnetic wave to return to its source is translated into a distance to the object.
Many of the radar sensors used at SensorLogic are considered Ultra Wide Band (UWB) Radar and span the frequency range 0.75 GHz to 11 GHz. UWB radar sensors use a very low energy level for short-range, high-bandwidth communications over a large portion of the radio spectrum. UWB radar can be used in applications such as radar imaging, target sensor data collection, precision locating and tracking applications.
SensorLogic uses Novelda Xe Thru UWB radar technology in many of our applications. Xe Thru Radar is a complete radar transceiver integrated on a single chip. The high bandwidth of the transmitted pulses offers unique penetration abilities and very high accuracy. Xe Thru radar can receive reflections from hidden objects like the heart in the human body or an object hidden behind an obstacle. This makes Xe Thru radar sensors particularly suitable for applications where light-based sensors fall short, such as through-the-wall detectors and in dark or dirty environments.
