22.7.6 Infrared Reconnaissance Set. The AADinfmred
line scanning detector is a passive detector of
energy in the far infrared region. The most striking characteristic
of the AADJ is its ability to detect thermal
activity, such as the hot-water discharge of a power
plant, the heat from the boiler of a ship, or the thermal
shadow left on a runway or ramp by a departed aircraft.
This characteristic can be used for many purposes, such
as determining the state ofreadiness of ships in a harbor,
judging the tratlic load of an airfield, determining the
quantity of P-O-L in storage tanks, determining whether
buildings are occupied,a nd separatingr ecentb omb craters
fiorn old ones. Since the AAD- IR detector cannot
determine the difference between the radiated energy
generatedb y activity and infmred (IR) energyr eflected
from the sun, some types of activity cannot be reliably
detected during the day.
The natural phenomenon of crossover will cause land
and water bodies to have identical IR signatures about
1 hour after sunrise and 1 hour after sunset. Missions
flown to detect land and water contrast (such as bomb
damage assessment on bridges) should avoid these
times by at least 2 to 3 hours.

The AAD-~ IR detector is not an all-weather sensor.
It cannot collect imagery through clouds or extremely
heavy haze. It is relatively unaffected by smoke.
At low altitudes, the AAD- IR detector is a relatively
good identification sensor. At higher altitudes, it may be
adequate only for detection or general identification,
depending on the type of target. A special ground tesolution
chart is included in Tactical Manual NWP-3-
22.5-F14A/B (NAVAIROl-F14AAA-1T).
The AADJ IR detector is folly roll and roll-rate stabilized
thorn a O0 to 20’ angle of bank in NFOV and O0
to 4O angle of bank in WPOV. Beyond angle-of-bank
hits, a steady bank angle will not seriously degrade IR
imagery. This feature makes it a highly practical sensor
for combat maneuvering situations. Because of varying
scale at the outer edges, the target should be placed
within the center 90” of the format.
The AAD- IR detector can be. reloaded in apptuximately
10 minutes and with the aircmft engines turning.
