AN/TPQ-50 Weapons Locating Radar System Characteristics and Employment 26 October 2021 ATP 3-09.12 I-7 TARGET CLASSIFICATION HOSTILE MODE I-23. The AN/TPQ-50 has the capability of providing friendly fire "did-hit data" with a TLE50 CEP of 50m for mortars (see table I-1 for other weapon TLEs). It has the capability of maintaining track on 20 simultaneous in-flight projectiles originating from separate sites uniformly distributed in the coverage area of the AN/TPQ-50. Table I-1. AN/TPQ-50 target location error Weapon Range (Km) TLE(m)* Mortar 60mm 0.5km 50m Mortar 81mm 0.5-8km 50m Mortar 120mm 1-10km 50m Cannon 155mm 1-6km 50m or 2% of range Rocket 122mm 1-10km 100m or 3.5% of range Rocket 240mm 1-10km 200m or 3.5% of range m – meter mm – millimeter km – kilometer TLE – target location error OPERATING THROUGH ELECTRONIC COUNTERMEASURES I-24. Operating through electronic countermeasures consists of detecting the presence of jamming or interference and performing actions to minimize or eliminate the effects of jamming. AN/TPQ-50 I-25. It is recommended to select a frequency that is not jammed. The cueing agent along with the frequency manager should conduct frequency deconfliction. I-26. The following bullets provide a concise summary of the AN/TPQ-50 capabilities: The AN/TPQ-50 can perform self-location functions given survey data. Operators can also manually bore sight the WLR and input location and orientating data in the event of automated systems failure. The AN/TPQ-50 operator can tailor the search sectors to enable coverage between 267 and 6400 mils. The AN/TPQ-50 operator can select a maximum of 18 sectors with a minimum of 1 sector. Establishing a priority enables the sensor to scan a particular sector more often than it would if scanning the entire 6400 mil detection span. The AN/TPQ-50 can upload DTED from external media the operator downloaded separately and use DTED Level 1, DTED Level 2, and SRTM data. The AN/TPQ-50 has a target track capacity that can detect and acquire a maximum of twenty projectiles within the search area at any given time. The system can recall from system storage, process and digitally transmit targets previously acquired in position while on the move. The AN/TPQ-50 can provide an acquisition message set to facilitate sense and warn mission. The AN/TPQ-50 can communicate and pass data with multiple subscribers on multiple nets simultaneously and interface through the AFATDS and battery computer system, operating on two digital and two voice communication nets. When an AN/TPQ-50 is working within an area protected by RAM-Warn activities, the AN/TPQ- 50 sends state vector data for indirect fire munitions to the FAAD control node. The FAAD uses this data, along with other sensor data, to correlate the position of the incoming indirect fire munitions and forwards the data to warn Soldiers in the affected area of the pending hazard. The system can electronically display tactical maps and graphic overlays of friendly and template enemy locations and boundaries and all FSCMs upon request. The AN/TPQ-50 provides jammer azimuth which facilitates jam strobe reporting. The AN/TPQ-50 provides built-in or integral data recording of all key operational, system readiness, and technical data without system degradation or operator distraction, as well as
