Multiple integrator ÒperformanceÓ will get worse if the noise goes up more, and better if the noise goes down some, but multiple looks are not
affected by what happens between the tone pips.
The top panel shows another
condition in which the noise between the tones goes up in intensity by 6 dB,
the bottom panel shows the case where the noise goes down by 6 dB between the
tones. Multiple integrator theory says that the changes in the noise level
will affect detection of the two tones, but multiple looks theory says it
wonÕt matter.
