echo amplitude

echo amplitude

[¦′ek·ō ′am·plə‚tüd]
(electronics)
In radar, an empirical measure of the strength of a target signal as determined from the appearance of the echo; the amplitude of the echo waveform usually is measured by the deflection of the electron beam from the base line of an amplitude-modulated indicator.

The echo amplitude is measured on the graph's horizontal axis, and depth is registered on the vertical axis.
19] uses fractional Brown motion to model echo amplitude fluctuation, on this basis, puts forward a classification method based on fractional Brown fractal dimension of echo in time and frequency domain (CMFBFD) for low-resolution radars, and gains a better classification effect for helicopters and civil aircrafts using the proposed method.
For the visualization and mapping we applied three signal processing algorithms: signal demodulation for echo amplitude mapping; short time Fourier transform (STFT) based algorithms for mapping of mean instantaneous frequency (MIF) and mean instantaneous bandwidth (MIB) of raw echosignal spectrum.
The isolines on the echo amplitude map are drown at levels from -34 dB to -46 dB in -3 dB intervals.
Each solution within the Phasor platform is compliant with all major inspection codes and is suitable for a wide range of tasks from simple echo amplitude comparison to complex DGS evaluation.
The echo amplitude was further integrated between TOT = 16.
Consequently, delamination or nonbonding in the seal causes a greater reflected echo amplitude to return to the transducer because of the higher acoustic-impedance difference between the discontinuous region in the seal and the polymeric package material.
In time domain imaging, where the echo amplitudes are recorded at a particular depth, solid-to-gas interfaces stand out in the monochrome acoustic image because they are white, and are typically much brighter than solid-to-solid interfaces, which typically reflect 20% to 80% of the ultrasound and are gray.
The MCT2100 compensates for a broad range of dynamic echo ensembles with echo amplitudes approaching the level of the desired signal.
