Appendix H H-14 ATP 3-09.12 26 October 2021 Table H-3. AN/TPQ-53 6400 mils coverage range and location accuracies Weapon Type Range Accuracy (Circular Error Probable 50) Mortar light (60mm) 3 to 10km 50m or .5% of range Mortar medium (81mm) 3 to 12km 50m or .5% of range Mortar heavy (120mm) 3 to 15km 50m or .5% of range Cannon light (105mm) 5 to 18km 75m or 1% of range Cannon medium (155mm) 5 to 20km 75m or 1% of range Cannon heavy (8 in) 5 to 20km 75m or 1% of range Rocket light (107mm) 5 to 20km 75m or 1% of range Rocket medium (122mm) 8 to 20km 75m or 1% of range km – kilometers mm – millimeter H-43. The operator can tailor the search sectors to enable coverage between 230 and 6400 mils in azimuth. The operator can select a maximum of 27 sectors, while in 360 degree mode, with a minimum of 1 sector. An individual sector can be no smaller than 230 mils (13 degrees). The WLR can detect and acquire six or more projectiles within the search area at any given time. H-44. The AN/TPQ-53 can acquire and track hostile and friendly mortar, cannon, and rocket projectiles throughout a 6400 mils search sector. The search sector can be moved and steered throughout the 6400 mil coverage without repositioning the vehicle or trailer on which the antenna is mounted. H-45. The AN/TPQ-53 is a multifaceted system which in 1600 mil modes has the ability to track mortars with a range of 500m to 25km, and artillery or rockets out to a range of 60km. The TPQ-53 provides flexibility for optimizing the operational mode to the tactical situation by offering additional search modes tailored specifically for short range or long range capabilities. For example, short range optimized mode allows for optimized tracking of short range, high angle rate targets. The operational mode should be determined during the MDMP and issued to the WLR section trough the RDO. H-46. The AN/TPQ-53 also has the ability to operate using a 6400 mil azimuth search sector with a designed to minimum range of 3km and maximum range of 20km. It is imperative for mode use to be determined during the MDMP and issued to the WLR section through the RDO. H-47. The AN/TPQ-53 software allows it to perform in 6 operating modes to include: 90 degree normal mode. 90 degree short range optimized mode. 90 degree long range optimized mode. 90 degree 107mm rocket mode. 360 degree normal mode. 360 degree weather mode. H-48. The 90 degree normal search mode utilizes 4 distinct waveforms which allow it to provide coverage from 500 meters to 50km. These waveforms overlap to provide very high revisit rates at close range and lower revisit rates at long range, ensuring the system will accurately locate targets from 500 meters-50km. H-49. The 90 degree short range optimized mode differs from the normal 90 degree mode, max ranges decreases to 25km. This mode provides additional elevation coverage at short ranges (500 meters-12km) and even higher revisit rates to improve probability of location and resulting accuracy. The 90 degree short range optimized mode is used to optimize locating high angle targets in close range and provide an 85% or greater probability of locating targets within 500 meters of POO.
