Appendix J J-14 ATP 3-09.12 26 October 2021 Figure J-10. Angle “T” J-56. Orienting data required for the friendly fire buffer and the actual fire mission can be sent by the FDC by voice or digital transmission. The data entered into the computer will either accept the search fence or reject it by displaying an error message. The radar operator must then coordinate with the FDC for adjustments to the firing data or orienting point that will allow the WLR to observe the rounds in the friendly fire mode. In friendly fire mode, the AN/TPQ-36performs three types of missions: Observe a high-burst registration (artillery airburst mode). Predict impact locations (artillery impact-predict mode). Observe a datum-plane registration (artillery datum-plane mode). J-57. These friendly fire mode missions support the two types of registrations conducted by the fire direction center. The radar high-burst registration provides "did hit" observations for the fire direction center high- burst registration. The radar impact-predict and datum-plane registrations provide "did hit" observations for the fire direction center mean-point-of-impact registration. The mean-point-of-impact calculations by the fire direction center differ for the two types of radar observation, because they correspond to different orienting points. J-58. When operating in friendly fire mode the radar provides friendly units with accurate actual burst, datum-plane, or predicted-impact location data. It has five mission sub-modes that are used to provide this data. The mission sub-modes are listed below: Mortar datum plane. Mortar impact prediction. Artillery airburst. Artillery datum plane. Artillery impact prediction. J-59. The AN/TPQ-36 can also observe adjust fire missions. The observation functions performed by the AN/TPQ-36 to observe an adjust fire mission are the same as an impact predict registration. HIGH-BURST REGISTRATION J-60. For a high-burst registration, the high-burst altitude above the registration point is the actual orienting point for the AN/TPQ-36. The high-burst altitude is located two probable errors in height above the
