A Preliminary Study of SAMTEC Postflight Refraction Correction.

摘要

Refraction correction is one of the important steps in metric data processing. The purpose of this refraction study is to investigate the current postflight refraction correction technique which is applied to SAMTEC radar data obtained from missile and aircraft tracking. This study serves as a preliminary step for future development to establish the minimum acceptable operational criteria on refraction corrections to meet range user's data accuracy requirements. In this task the following were investigated: the differences between refraction corrections based on the rawinsonde profile and several model profiles, the errors in refraction corrections based on rawinsonde-measured profiles, and the minimum height required for rawinsonde measurements.
