Analysis of the accuracy of direction finding of random fields by means of two-channel single-pulse systems
Abstract
Each type of single-pulse direction finding system is viewed as consisting of an antenna sensing subsystem, a subsystem of information conversion, and a measuring subsystem. Since there may be three types of sensing and measuring subsystems (amplitude - A, phase - Ph, and combined - C), each system is labeled by two letters, where the first letter designates the type of antenna sensing subsystem and the second stands for the type of measuring subsystem. The paper deals with the analysis of the accuracy of single-pulse direction finding systems of the AA, PhPh, APh, and PhA types employing linear apertures. Allowance is made for spatial signal fluctuations and for the internal noise of the receiving system. Superior accuracy of the AA system employing a logarithmic measuring subsystem is established.
