Bandwidth reduction strategies for the transmission of land-based marine radar data
1983
A technique for reducing the bandwidth requirement for the transmission of digital shore-based marine radar data is presented. It is found that the removal of ground clutter, run length encoding and scan-to-scan averaging results in a reduction of about a factor of 20, allowing the use of a 10 kHz telephone line in place of a microwave-link communication system with no loss of image quality.
