AN/TPQ-53 Weapons Locating Radar System Characteristics and Employment 26 October 2021 ATP 3-09.12 H-11 H-35. Figure H-7 depicts how the AN/TPQ-53 6400 mil azimuth coverage is achieved. Beams are steered electronically forward and backward of the center beam by 30 degrees as shown, while the array is mechanically rotating at 30 revolutions per minute. This method illuminates the targets three times per scan. The system operates in a track-while-scan mode with a fixed radar timeline which allows for the volume search every scan. Figure H-7. Azimuth coverage of the AN/TPQ-53 in 6400 mil mode AN/TPQ-53 DETECTIONS AREA H-36. The possible detection area is a three dimensional space defined by the minimum and maximum range, search sector, and the vertical scan of the WLR. Planning ranges are used for the purpose of this discussion; however, the maximum planning range for the WLR is not an absolute. It is the range at which the probability of detection becomes low enough to be unsuitable for planning purposes. Nonetheless, objects may be detected beyond the maximum planning range. Conversely, objects within the planning ranges may not be detected. Listed below are the planning ranges for the various operational modes of the AN/TPQ-53: 90 Degree Normal - 0.5 to 20km for mortars, 0.5 to 34km for artillery, and 0.5 to 50km for rockets. 90 degree short range optimized mode - 0.5 to 20km for mortars, 0.5 to 25km for artillery, and 0.5 to 25km for rockets. 90 Degree Long Range Optimized Mode - 0.5 to 20km for mortars, 0.5 to 34km for artillery, and 0.5 to 60km for rockets. 90 Degree 107mm Rocket - 25 to 34km for artillery, and 25 to 50km for rockets. 360 Degree Normal - 3 to 15km for mortars, 5 to 25km for artillery, and 5 to 20km for rockets. 360 Degree Weather - 3 to 15km for mortars, 5 to 25km for artillery, and 5 to 20km for rockets.
