Why Does Large Dynamic Range Improve Visibility?

The majority of people would not initially think of the Microchiroptera bat species when providing examples of evolution’s astounding achievements. However, its echo-locating system makes it the best at seeing in the dark out of all mammals, meaning it is more easily able to locate the smallest insects for food.

A similar principle guides the function of radar sensors. The better they can hear their “locating sounds” – or, if we are talking about Radar sensors, the greater the dynamics – the more visible the level echo becomes.

In radar level measurement, dynamic range makes the difference. When the view is blocked by build-up and condensation on the antenna, for example, or in poorly reflecting media, the sensor’s dynamic range can provide the required sensitivity in order to detect even the smallest signals reliably.

In this manner, VEGA’s 80 GHz Radar sensors, equipped with their uniquely high 120 dB, can achieve a full view under any process conditions.

As it happens, in many bat species, there are significant differences in dynamics. Similar to the VEGAPULS 64 80 GHz Radar sensors, their loudest echo-locating calls can reach as high as 120 dB.
