Appendix A A-2 ATP 3-09.12 26 October 2021 TARGET INDICATOR PROCESSING A-4. The FA BN FSE receives a shelling report from one of the unit's observers. The FA BN FSO may direct that the report be forwarded to the FAB or DIVARTY (or the designated counterfire HQ). ADVANCED FIELD ARTILLERY TACTICAL DATA SYSTEM AUTOMATIC PROCESSING OF TARGET INDICATORS A-5. AFATDS always performs certain functions when a target indicator is initially received, whether it was received from an observer or created through operator input. When AFATDS receives target indicator data, some of the information required to process the indicator may or may not be present. AFATDS automatically determines missing information based on the reporting observer's unit data and default data files. Missing information is determined as follows: Target Indicator Number - If the received target indicator does not have a target indicator number, one is assigned based on the next available target indicator number from the target indicator number block. The target indicator number must always begin with "II". If a target indicator is received with a number that does not begin with "II", the number will automatically be replaced with an "II" number. AFATDS maintains a target indicator numbering block, which the operator cannot edit. This block goes from II0000 to II9999. Note. When you enter a target indicator into AFATDS do not enter a target number (AFATDS will automatically number the indicator). Target Indicator Decay date time group - If the target indicator decay date time group for the target indicator is not provided, AFATDS computes the date time group by adding target decay guidance for the target type to the date time group of acquisition or report. The date time group of the report will default to the current time if not provided. Target Type - If the received target indicator does not specify a target type, one is assigned based on the following rules. If the caliber of the mortar is reported, AFATDS will determine the target type as shown in table A-1. Table A-1. Mortar caliber target type mapping Caliber Target Type 108 - 150mm Heavy 61 - 107mm Medium Less than 60mm Light Not given Unknown mm – millimeter Sensor Directional Error - If the target indicator does not include the sensor directional error (mils) then it is determined based on the default value for the reporting sensor's unit data or unit type. Sensor Location - If the sensor location at time of report is not provided, then that sensor unit's most current location is used to determine this value. If no location for the reporting unit is available, the target indicator report is discarded. TARGET SIMILARITY A-6. AFATDS uses target similarity to determine if targets should be combined, or if target indicators are close enough to generate target data. The matrix number is the individual number for that target type. The matrix is also used for target duplication checks. DIRECTION AND DISTANCE A-7. The direction and distance of the target indicator ray is determined by: Direction of ray originating from the shell impact location.
