OTRC Signal[ ] =
d. Normalize “OTRC Signal[ ]” as the maximum and minimum values of “OTRC
Signal[ ]” are converted to 1 and 0 respectively. The obtained data is called
“Normalized OTRC Signal[ ].”
5. “Squeezed Signal[ ]” and “Normalized Squeezed Signal[ ]” Calculation
a. Remove “Noise Floor” from “Squashed Data[ ]” using the following equation:
Squashed Data1[ ] =
b. Perform smoothing for “Squashed Data1[ ].” The result is called “Squashed
Data2[ ].”
c. “Squeezed Signal[ ]” is derived from the following equation:
Squeezed Signal[ ] =
d. Normalize “Squeezed Signal[ ]” as the maximum and minimum values of “OTRC
Signal[ ]” are converted to 1 and 0 respectively. The obtained data is called
“Normalized Squeezed Signal[ ].”
6. “OTRC Noise[ ]” and “Normalized OTRC Noise[ ]” Calculation
a. Remove “Noise Floor” from “Side Noise ID[ ]” using the following equation:
Side Noise ID1[ ] =
b. Perform smoothing for “Side Noise ID1[ ].” The result is called
“Side Noise ID2[ ].”
c. Remove “Noise Floor” from “Side Noise OD[ ]” using the following equation:
Side Noise OD1[ ] =
d. Perform smoothing for “Side Noise OD1[ ].” The result is called
“Side Noise OD2[ ].”
e. Compose “SideNoiseID2” and “Side Noise OD2” using the following equation
(the composite data is called “Side Noise2[ ]”):
If Side Noise ID2[] > Side Noise OD2[]
Side Noise 2[ ] = Side Noise ID2[ ]
Else,
Side Noise2[ ] = Side Noise OD2[ ]
f.
“OTRC Noise[ ]” is derived from the following equation:
OTRC Noise[ ] =
g. Normalize “OTRC Noise[ ]” as the maximum and minimum values of “OTRC
Signal[ ]” are converted to 1 and 0 respectively. The obtained data is called
“Normalized OTRC Noise[ ].”
7. “Squeezed Noise[ ]” and “Normalized Squeezed Noise[ ]” Calculation
a. Obtain “Squeezed Noise[ ]” by combining two “OTRC Signal[ ]” profile plotted at
±
squeeze position.
b. Remove “Noise Floor” from “Cockpit Noise[ ]” using the following equation:
Cockpit Noise1[ ] =
c. Perform smoothing for “Cockpit Noise1[ ].” The result is called “Cockpit
Noise2[ ].”
d. “Squeezed Noise [ ]” is derived from the following equation:
Squeezed Noise [ ] =
e. Normalize “Squeezed Noise[ ]” as the maximum and minimum values of “OTRC
