Electromagnetic Radiation Effect on Foraging Bats - Recent Advances and Issues in Environmental Science - page 71

Figure 4. The response of bats to: (a) short pulse length (0.08 μs) radar signal from a rotating antenna.
(b) short pulse length (0.08 μs) signal from a fixed antenna. (c) medium pulse length (0.3 μs) signal
from a fixed antenna. Each bar represents the difference in foraging rate per unit time as reflected by
the difference in FBR between control and experimental trials. A negative value indicates that bat
activity was higher during the control trial than during the experimental trial when the radar was
switched on.
