QUESTIONS AND CORRECT ANSWERS
Pulse Width - CORRECT ANSWER The active transmit time or duration of the
electromagnetic pulse
Rest time - CORRECT ANSWER the non-transmit time or interval between electromagnetic
pulses
Wiens Law? - CORRECT ANSWER Calculates wave length of max radiation.
Planks Law? - CORRECT ANSWER Dictates the shape of the spectral radian emittance vs.
wavelength curve.
Stefan-Boltzmann's Law? - CORRECT ANSWER Gives us the integral of exitance.
Beer Lambert Law? - CORRECT ANSWER Gives us the transmittance as a function of
wavelength, environmental attenuation factors, and range to target.
Spot Jamming - CORRECT ANSWER Jamming using a narrow bandwidth.
Barrage Jamming - CORRECT ANSWER Jamming that is spread over a large bandwidth.
Swept Spot Jamming. - CORRECT ANSWER Jamming in which switches from narrow to large
bandwidth.

dazzling, range approximation
T or F laser beam spreading occurs in the same manner as white light - CORRECT
ANSWER False
What is thermal cross over? - CORRECT ANSWER When the environment heat is the same as
the target temp thus no contrast.
