A Gunner Model for Tracer-Directed Antiaircraft Artillery Fire with Interrupted Observations.
Abstract
In a tracer-directed fire mode, the gunner plays the role of a conventional tracker and a lead angle computer. Tracer rounds are fired continuously by the gunner to provide an additional observation channel. In the event of repeated observation interruption, via blanking the target from the optical display, the gunner's performance is considerably degraded. In this report, a gunner model is designed which consists of a reduced-order observer, a linear feedback controller, and a remnant noise element. The effect of observation interruption is modeled by degrading the model parameters related to the observed states. An exponential decay form is assumed for these parameters. Model parameters and associated time constants are identified from empirical data via a least-squares minimization algorithm. Model predicted tracking and tracer errors are compared with empirical data and found in general agreement with each other. From these results, it is concluded that the gunner model can be used accurately and efficiently in the analysis of the effectiveness of AAA weapon systems under observation blanking. (Author)
