echo intensity

[¦ek·ō in′ten·səd·ē]
(electronics)
The brightness or brilliance of a radar echo as displayed on an intensity-modulated indicator; echo intensity is, within certain limits, proportional to the voltage of the target signal or to the square root of its power.

echo intensity
The brightness or brilliance of a radar echo as displayed on an intensity-indicated modulator. Echo intensity is, within certain limits, proportional to the voltage of the target signal or to the square root of its power. Bigger targets will have greater intensity vis-à-vis smaller targets. The echo intensity is also dependent on the target aspect. It will be the maximum when the target is flying across the radar beam and the minimum when it is flying directly toward or away from the radar. See radar cross section.

Plaque Property: (1) Mixed plaque: if the same section shows multiple kinds of echo, the plaque is mixed plaque; (2) Calcified plaque: echo intensity of the plaque exceeds adventitia echo of coronary artery wall, accompanied with acoustic shadow at the rear of the plaque; (3) Fiber plaque: echo intensity of the plaque is similar to adventitia echo of coronary artery wall; (4) Lipid plaque: plaque echo is lower than adventitia echo of coronary artery wall.7
Setting the original data to [d.sub.o] ([x.sub.o],[y.sub.o],[z.sub.o]), where [x.sub.o], [y.sub.o] respectively represent the data elements in a radar map P (1000 x 1000) within the row and column coordinates; [z.sub.o] denotes the data element where the radar map number [P.sub.no]; [d.sub.o] denotes the echo intensity detected by the radar.
When submucosal lesions are present in the stomach, especially in the fundus of the stomach, the echo intensity similar to that of the spleen under EUS should alert the operators of the possible presence of an accessory spleen even when the patients have a medical history of splenectomy.
This process uses extracted amplitudes from ADCP as echo intensity (EI) and converts it to SSC through calibration based on the sonar equation principle [6].
Measures of muscle cross-sectional area (CSA) and echo intensity (ECHO) were obtained using a sweep of the muscle in the extended field of view mode with gain set to 50 dB and image depth to 5cm.
Figure 8 is a brief schematic representation of Mode B, showing a hypothetical case of three lineal transducers imaging echo dots, where luminosity corresponds to echo intensity.
Namely, if [[theta].sub.T] is fixed, the ratio of echo intensity from the left part receiving elements to those from the right part receiving elements will be invariable even when the pose angle [[theta].sub.P] of the sphere or tophat varies.
As a result, any change in the relative position of the target to the bat reflected that large sonar edge back at the bat, delivering the largest possible change in echo intensity.
A factor in the accident was air traffic controller's failure to issue extreme weather radar echo intensity information displayed on the controller's radar to the pilot." The NTSB's probable cause statement is remarkably similar to the one associated with Scott Crossfield.
