What is Radar Technology?

Radar sensors , Radar technology is an excellent measuring technology for motion detection. In radar detection, an antenna actively emits high-frequency electromagnetic waves. If they hit an object, this results in the signal being reflected (as an echo), which the sensor then receives. The reflecting signals contain different information than before and can be used to conclude that a movement is taking place. Measurements are carried out continuously and in real time. Radar detects any change in moving people’s or objects’ positions. The radar-based data can be used as a digital trigger through appropriate signal processing.
This measurement method boasts several advantages compared to competing technologies:

• Radar waves are invisible to humans and pass through various materials, for example plastic. The measurement is carried out without contact, by a sensor that is integrated behind a plastic housing and goes completely unnoticed by the person generating the movement signal.
• This measurement method outputs only individual radar detection or object clusters. No visual image can be derived from this information, meaning that monitoring is carried out in an anonymous manner, ensuring data protection.
• Rain, fog, snow, wind, and ice generally don’t restrict the functionality of radar sensors. They reliably detect movement despite adverse weather conditions. Even extreme heat or cold don’t impair the technology.
• Radar sensors require no maintenance, and once they are configured, there is no need to check them regularly.
• The technology keeps working independently of lighting.
• Radar waves have long ranges. With this technology, large areas can be monitored and objects 150 meters away can be positioned, for example, with just one sensor. But the sensors are also suitable for close range.
• Radar boasts very good measurement quality due to its high resolution and extensive information collection. The technology provides precise and reliable measurement results for positioning objects and persons. The sensor solutions transmit data on speed, direction of movement, distance, and angular position.

More and more security equipment manufacturers are incorporating radar into their products. At the same time, the radar experts are managing to offer the sensors at more affordable prices. A very broad array of radar solutions is thus conquering the industry. Innosent already offers a wide range of radar motion detectors, providing the right solution for every application.
The various motion detectors can be used, for example, for lighting control in the garden or courtyard, but also in combination with simple alarm systems. A Tracking Radar application can be considered for more complex security monitoring from near to far.
