A Fiber Optic Beam Controller for Phased Array Radars.

摘要

The objective of the research documented in this report was to determine if the accurate time delay and the broad bandwidth of fiber optics could be exploited to construct a time delay phasing device for a microwave antenna. Time delay phasing of microwave antennas is highly desirable because there is no coupling between the signal bandwidth and the antenna beam angle for a time delay antenna. This enables radiation of broad bandwidth signals necessary for close range resolution at precise angles from a phased array mirowave antenna.
