Table 3.

Standard deviation of wingbeat frequency measurement errors for W-band and S-band radars.

Statistical measure Amplitude-based method Phase-based method
W-band radar S-band radar W-band radar S-band radar
Standard deviation (Hz) 0.89 1.29 0.33 1.06

Note: These statistics of the differences between the stroboscope and radar measurement values are with one datum for each specimen (n = 13 for W-band and 7 for S-band).
