Video Tape Recording Techniques for SEASAT Radar Data

摘要

A dual channel ARVIN/ECHO WRR-441 video tape recorder was used in a system to record SEASAT radar data. The video recorder channels were limited to 6 MHz bandwidth whereas the radar data covered 20 MHz. By designing a phase quadrature recording/play back system an effective bandwidth of 12 MHz was realized which covered the main lobe of the sin X/X radar signal spectrum. (Author)
