Sentence examples for echo rates from inspiring English sources

This should reduce any statistical error in wind estimates associated with low echo rates for the majority of the height distribution.

This agreement is more evident with the Davis 55 MHz meteor comparisons, possibly due to the interleaved experiment sequence run on that radar and the typically lower echo rates when compared with observations made at 33.2 MHz.

The line plots on the right-hand side represent the corresponding 33.2 MHz (top right) and 55 MHz (bottom right) mean echo rates for each height averaged over the year.

This suggests that the echo rate at each time height bin has a significant impact on the quality of the wind estimates produced by the radars.

The combination of this mode of operation and the higher transmit power level resulted in a higher observed echo rate in each hour-height data bin over the observation period.

Together with the Davis comparison, this suggests that the echo rate, particularly in the extremities of the height distribution, plays an important role in the statistical reliability of the wind estimates.

Although echo rate appears to be a major contributor to the quality of meteor wind estimates over the height range of the meteor distribution, other factors such as sampling sequences, geophysical phenomena, system configuration, and seasonal variations in count rate are believed to play a strong part in the quality of these estimates.

For example, for all of 2006, the mean daily count was around 9600, with a peak mean daily echo rate of about 1700 meteor detections near 90 km for the 33 MHz radar, and a daily mean count of about 2100, with a peak mean daily count of about 390 meteor detections near 88 km for the 55 MHz radar, noting also that the meteor peak detection height decreases with increasing frequency.

This was possible as the echo rate is at a minimum at the radiant point, and a maximum at 90 degrees to it.

Varying levels of emissions from transport also echo motorisation rates.

Larger meteor echo detection rates better constrain the solutions and thereby increase the accuracy of wind estimates.
