SummaryIn 5 roosting bats the resting frequency, that is the mean frequency of the cf-portion of consecutive sounds, is kept constant with a standard deviation which varies between 30–120 Hz in different bats and at different days. In 15 bats the emitted sounds were electronically shifted in frequency and played back as artificial echoes. Upward frequency shifts were responded by a decrease of the emission frequency. This frequency compensation occurred at frequency shifts of up to 4400 Hz in… Expand

Dynamic properties of the compensation system for doppler shifts in the bat,Rhinolophus ferrumequinum
Summary1.Echolocation sounds of the batRhinolophus ferrumequinum were played back to the bat as artificial echoes shifted in frequency by a few kHz (0–4 kHz) without distortion of the amplitude andExpand
Spectral and temporal gating mechanisms enhance the clutter rejection in the echolocating bat, Rhinolophus rouxi
The temporal and spectral gating in Doppler shift compensation behaviour is discussed as an effective mechanism for clutter rejection by improving the processing of frequency and amplitude transients in the echoes of horseshoe bats. Expand
Fine control of call frequency by horseshoe bats
The results indicate that Doppler-shift compensation is mediated by a pair of (echo)frequency-specific sigmoidal functions characterized by a threshold, a slope, and an upper limit to the maximum change in frequency that may occur between successive calls. Expand
Adaptive echolocation sounds in the batRhinopoma hardwickei
Evidence is presented that shows thathinopoma hardwickei flying in groups regulate the frequency of their individual CF-components and in this way they avoid jamming one another. Expand

The range of the Doppler-shift compensation system is limited by the delay due to acoustic travel time to about 4 m distance between bat and target, when compared with data on the orientation pulse length during target approach from Schnitzler (1968). Expand

Precise Doppler shift compensation in the hipposiderid bat, Hipposideros armiger
To investigate the precision of Doppler shift compensation in Hipposideros armiger, recorded the echolocation and flight behaviour of bats flying to a grid, reconstructed the flight path, measured the flight speed, calculated the echo frequency, and compared it with the resting frequency prior to each flight.

Effects of echo intensity on Doppler-shift compensation behavior in horseshoe bats.
The results indicate that, even at the highest intensity levels, relatively minor changes in echo intensity critically influence frequency compensation during normal DSC. Expand
Frequency tracking and Doppler shift compensation in response to an artificial CF/FM echolocation sound in the CF/FM bat,Noctilio albiventris
Bats in flight lower the frequency of their emitted pulses to compensate for Doppler shifts caused by their own flight speed and systematically shift the frequencyof their emitted CF component so that the echo CF frequency returns close to that of the CF component of the artificial CF/FM pulse, over the frequency range where tracking occurs.

An electronic target simulator was used to produce artificial echoes for the echolocating bat, Rhinolophus ferrumequinum, and it changed the frequency of the constant‐frequency portions of its outgoing orientation sounds to restore the CF portions of returning echoes to the bat's preferred frequency.
