Abstract

Statistical models are developed for the random spatial variations in refractivity in the troposphere, and are used to derive spatial correlation functions for the errors in range measurement and interferometer angle measurement. These are then used to analyze the relative errors between two tracked targets, for application to command-guided intercept problems. It is shown that multilateration, using range measurements, yields much smaller relative errors than does the interferometer approach
