Sentence examples for strength of the echo from inspiring English sources

A racon can greatly increase the strength of the echo from a poor radar target, such as a small buoy; it is also helpful in ranging on and identifying positions on inconspicuous and featureless coastlines and in identifying offshore oil and gas rigs.

In small scale studies (where the effect of depth-wise attenuation is effectively ignored), a peak is measured in the strength of the echo responses at intermediate concentrations, due to a balance of the backscatter and attenuation components on the overall signal.

The strength of the echo determines the brightness of the echo displayed in ultrasound images.

The strength of the echo is related to the differences in acoustic properties of the medium: The greater the difference, the stronger the echo.

The distance at which a bat can detect airborne prey depends on the size and echo reflectance of the insect (the so-called target strengths), on the echo detection threshold of the bat's auditory system and, importantly, on the frequency and intensity of the echolocation calls [1], [2], [3], [4], [5], [6].

These experiments showed that the difference in the strength of the echoes from the moth and its surroundings varied depending on the texture of the surface.

They further speculate that at obtuse angles, the smooth leaf surface contributes to the 'mirror effect' (Siemers et al., 2005), which increases the relative strength of the target echo over the substrate clutter echo, as the latter is mirrored away at oblique angles.

For a user-specified number of scans the program computes a temporal mean and mean deviation of the strength of the radar echo from user-defined windows of samples and pulses across the entire scan.

Furthermore, the strength of the clutter echoes was varied from −20 dB to 20 dB relative to the target echo.

These plots show that, as the strength of the clutter echoes increases, the variability in the received spectrum increases also.

In addition, measurements from three different look angles have made it possible to study the aspect angle dependence of the echo strength and thus indirectly the plasma dynamics around the meteor head and fragmentation of individual meteors in the atmosphere (Kero et al. 2008a, b).
