echo intensity

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.
