Анализ потенциальной точности измерения угловой координаты

Abstract

A comparative analysis of the potential accuracy of measurement of the angular coordinate radar target at discrete and linear scanning of antenna beam was fulfilled. On the basis of the provisions introduced for two-beam likelihood function and expression of the Cramer - Rao, the formula for the variance of the angular coordinate assessment was obtained. An approximation of the antenna pattern form is proposed. The calculation results show that at discrete-beam scanning the accuracy of angular position measurement is higher than at the linear scanning.
