(2) Speed.
d. WHEN:
(1) Time of contact report of information in the report.
All elements should be amplified if possible or required (e.g., type, class, nationality, Doppler,
behaviour, time late, etc.).
6240 THE PROCESS OF PICTURE COMPILATION
Picture compilation can be subdivided into five processes:
a. Detection.
b. Localization.
c. Recognition.
d. Identification.
e. Dissemination.
6241 DETECTION
a. The detection process includes the employment of sensors in a certain area or volume, to
determine the presence or absence of contacts or contact-related data. The presence of contacts or
contact-related data should stimulate the other four processes.
b. The detection process can be aimed at the detection of specific contact(s) in a clear-cut area.
c. Probability of gaining contact depends on the following:
(1) Sensor probability of detection (sensor’s sweep width).
(2) Coverage factor.
(3) Frequency of cover.
(4) Duration of mission.
(5) Type and behaviour of target.
(6) Time late and last known position.
(7) Operator performance.
(8) Environmental and geographic factors.
d. These factors should be applied to the conduct of scouting missions against surface and
subsurface targets. As it is often impossible to assign values to these factors because of the problems in
predicting sensor performance and target behaviour, the probability of gaining contact is difficult to
determine. However, broad values for both coverage factor and frequency of cover may be required in
planning.
