Abstract: During fiscal years 1998 and 1999, an effort was conducted as part of a technology program annex with the U.S. Army Test and Evaluation Command to develop gunner tracking models for the U.S. Army Research Laboratory's Combat Vehicle Engineering Simulation (CVES). CVES contains engineering models of the fire control system, chassis-suspension, and the gunner for the M1A1 combat tank and the A3 version of the Bradley fighting vehicle system. This effort addresses the gunner model for the M1A1. Gunner models were developed using the Xmath(TM) interactive system identification algorithms from the MATRIXx(registered) software package along with measured gunner tracking error and estimated target rate data (gunner handle control output). The resulting gunner tracking models are shown to be more accurate than the existing gunner tracking models used in CVES for two of the three maneuvering target paths that were considered in this study. Furthermore, the results demonstrate that usable models can be developed using the techniques discussed in this report.
