Effects on SADARM Trajectory Simulations With Local RAOBs and BFM Data for the RDAP/LUT Firings
Abstract
The research described herein was funded by the Office of the Project Manager, Artillery Munitions Systems. The U.S. Army Research Laboratory was tasked to perform meteorological (Met) analyses of data collected during the Sense and Destroy Armor (SADARM) Reliability Determination/Assurance Program (RDAP) and Limited User Test (LUT) artillery firings in January and April/May, 2000, at Yuma Proving Ground, Arizona. Actual SADARM impact data were compared against predicted impacts derived from the general trajectory model Version 3 (GTRAJ3) artillery trajectory simulation program (a simulator developed by the U.S. Army Armament Research, Development, and Engineering Center that relies heavily on Met data input). Two types of Met data were entered in the GTRAJ3 in order to test which type most accurately represented the "real" atmosphere. They were measured radio wind sounding (rawinsonde) balloon observations (RAOBs), which are the type of Met data currently used for aiming calculations by Army artillery units, and data generated by a Met forecast model, called the Battlescale Forecast Model (BFM).
