Method of signal treatment and processing using the ROSAR system

摘要

A method of signal conditioning and processing uses a ROSAR system for obtaining high-resolution elevation data using a fixed transmitting antenna, without requiring a turnstile. A telescope-like extensible transmitting antenna having large vertical dimensions illuminates an area to be imaged in a fanned pattern, creating overlapping elevation sectors. Reflected signals are relayed to a fixed receiving antenna via rotating transponders.
