Appendix H H-16 ATP 3-09.12 26 October 2021 Figure H-9. Friendly projectile tracking H-59. When executing a friendly fire mission in 360 degree mode, the WLR utilizes the hostile search fence to perform friendly fire registration, identifying the friendly round based on the expected target trajectory. H-60. When operating in the friendly fire mode the WLR provides friendly units with accurate predicted impact location data. The AN/TPQ-53 supports 3 missions that are used to provide this data. The missions are listed below: Mortar impact prediction. Artillery impact prediction. Rocket impact predication. H-61. See the AN/TPQ-53 operator manuals for the correct friendly fire mission procedures. OPERATING THROUGH ELECTRONIC COUNTERMEASURES H-62. 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-53 H-63. The WLR can indicate jamming by any or all of the following: displaying a line at the jamming azimuth on the operational display, jam strobe message (azimuth, frequency, time) in the jammer database, the jammer indicator displaying the number of active jammers, or the electromagnetic attack indicator indicating an Active status in the operations screen. To avoid degradation of WLR performance the following tactics may be used: Keep the WLR's electromagnetic attack countermeasures features enabled. Avoid operation within line of sight or in the same sector as the jammer. Operate on a different frequency than the jammer. Use deception. H-64. Keeping the WLR's electromagnetic attack countermeasure functions enabled allows for activation of the jam strobe and electromagnetic protection functions. The jam strobe identifies the azimuth of the jamming while the electromagnetic protection functions serve to remove the effects of interference from the jammer.
