Through the use of the sonar bats are
very easy victims of wind turbines. For between
sending the signal and flying through the rotor blades rotate them further, and so the risk of a collision is very high. They are
also due to their low body weight and its large wing
surface easily attracted by the pull of the turbine and dying from the effects of turbulence and the
subsequent collision.
Since migrating bats are particularly affected by
this problem, with the help of radar systems, the collision of the animals can be prevented by targeted stopping the systems.

The data is collected through field observations and with the help of technical systems. These include, but are also bat detectors, radar and camera system. More on this topic can be found here.
VESPER - Vertical bird and bat radar
This radar system was specially developed for the identification and differentiation
of bird and bat species. Based on the wing beat
frequency, the system distinguishes birds, bats and insects. The system
may stop falling below a safe limit, the wind
turbine through a SCADA link.
MERLIN - Horizontal and Vertical
radar
This radar system is composed of a horizontal and a vertical radar. Through
the data collection and processing in the control unit, therefore, the size, speed and altitude of birds and bats are determined. This
system also has a link with the SCADA system WKA is
possible.
DTBird - Camera system
