RADAR

Orders begin with RADAR for the station in the conning tower, or with SUGAR DOG for the station in the control room.

REPORTS typically begin with the name of the radar station or the specific radar equipment from which the reports originate.

The radar equipment should be referred to as follows:

SUGAR DOG APR
SUGAR JIG BK
SUGAR TARE BN

When a rapid series of reports is coming from a radar operator, the conning tower may direct the operator to omit this identification. The identification is always omitted in reporting plane contacts because it is understood that all plane reports come from SUGAR DOG.

INITIAL CONTACTS

Upon making a contact, the SUGAR JIG operator immediately reports contact, bearing and range. The SUGAR DOG operator reports contact and range. As soon as possible, he adds whether the target is opening, closing or standing still.

SUPPLEMENTARY REPORTS

Without further orders, radar operators report all additional information as soon as it is observed. This includes:
1. Identification and further details concerning targets, such as size of ship, number of planes etc.
2. Revised judgment as to identification, size, number etc.
3. Marked changes in course, such as change in range rate.
4. Lost contact, giving range and bearing of last observed position
5. Evidence of radar jamming, interference or deception.
6. Failure or improper operation of equipment.
