AN/TPQ-53 Weapons Locating Radar System Characteristics and Employment 26 October 2021 ATP 3-09.12 H-17 Line of sight issues can be avoided by selecting optimal WLR sights. Relocating the WLR to avoid jamming may or may not be possible based on the tactical situation. Changing WLR frequencies will sometimes help avoid the jammer's operating frequency. If these steps do not work, it may be possible to fool the jammer by ceasing to radiate for a few minutes, change frequencies, and then resume operations. This may help prevent the jammer from staying on the WLR's frequency. H-65. The following bullets provide A concise summary of the AN/TPQ-53 capabilities: Transportability: The AN/TPQ-53 can be shipped worldwide by ground, rail, water, and air. The AN/TPQ-53 can be air transported by large cargo airplanes. The AN/TPQ53, in its MEG configuration, can be air transportable in a single C-130 sortie, and the MEG/SOG configuration can be air transported in a single C-17 sortie without disassembly and with drive-on and drive-off capability. It can be placed in a travel configuration prepared to convoy within 2 minutes of off- load. Emplacement and Displacement: Four operators can emplace and bring the system in to full operation in 10 minutes. Four operators can displace the system into a travel configuration and be ready for movement within 5 minutes. Add an additional 15 minutes for inclement weather or nighttime operations. Self-surveying and Orientation: The AN/TPQ-53 can perform self-location functions. Operators can also manually bore sight the WLR and input location and orientating data in the event of automated systems failure. Search Sector Tailorability: The AN/TPQ-53 operator can tailor the search sectors to enable coverage between 230 and 6400 mils. The AN/TPQ-53 operator can select a maximum of 27 sectors with a minimum of 1 sector. Tailoring a search sector enables the sensor to scan that particular sector more often than it would if scanning the entire 6400 mil detection span. An option exists for search sectors to be automatically defined by the system based on the current operating mode or for the operator to override the automatically generated sectors and manually define them. DTED: The Q-53 can upload DTED from external media the operator downloaded separately and use DTED Level 1, DTED Level 2, and SRTM data. Radar Terrain Following Data: AN/TPQ-53 can implement and store electronic radar terrain following data. The operators can also manually input terrain data. The system defaults to the most accurate data. In 90 degree modes, search beams automatically follow the terrain mask in use. Did-Hit-Data Capability: The AN/TPQ-53 provides did-hit-data (projectile impact location) of friendly indirect fires in the 1600 mil mode to an accuracy of 30m or .3% of range. In the 6400 mils mode, the AN/TPQ-53 will achieve an impact location accuracy of 50 meters or 0.5% of range for mortars and an accuracy of 75 meters or 1% of range for cannons and rockets. Impact Point Prediction: For hostile fire, the projectile impact point accuracy is typically within 250 meters or 2% of range. Locating non-standard munitions: The system can track and locate projectiles launched with nonstandard quadrant elevations and high muzzle velocities. False Location Rate: The AN/TPQ-53 has a false location rate of no more than one every 6 hours in both modes. Combat experience and testing has demonstrated that similar WLRs and RF emitters of the same band, rotary and fixed wing aircraft can cause an increase in false locations. Height Correction Automated or Manual: The WLR automatically height corrects all targets or provides the operator with the option to manually input corrections in order to achieve the actual firing location with the use of Digital Terrain and Elevation Data Level 1, Digital Terrain and Elevation Data Level 2, and SRTM data. Transmit Targets on the Move: The system can recall from system storage, process and digitally transmit targets previously acquired in position while on the move. Sense and Warn: Radar can provide an acquisition message set while in 1600 mils or 6400 mils mode to facilitate sense and warn mission. Voice and Digital Communications: The AN/TPQ-53 can communicate and pass data with multiple subscribers on multiple nets operating on one digital and one voice communication nets. State Vector Capability: When an AN/TPQ-53 is working within an area protected by RAMWarn activities, these WLRs send state vector data for indirect fire munitions to the FAAD control node.
