Abstract
Statistical models are developed for the random spatial variations in refractivity in the troposphere, and are used to derive spatial correl ation 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 interc ept problems. It is shown that multilateration, using range measuremen ts, yields much smaller relative errors than does the interferometer a pproach.
