Performance Analysis of a Split-Beam Automatic Target Follower in Adverse Acoustic Environments.

Abstract

Steady-state bias and random errors are derived for an analog automatic target follower (ATF) whose inputs are sample functions of a stationary zero mean Gaussian random process. The result is in the form of two coupled transcendental equations that include the effects of correlated noise, interfering targets, and multipath. Specific values of the bias and random errors require the simultaneous solution of these two equations for any given set of acoustic conditions. Several examples are cited to illustrate the performance and threshold characteristics of a typical ATF operating in adverse acoustic environments. (Author)
