Radar imaging using pseudo‐coherent marine radar technology [PDF]
IET Radar, Sonar & Navigation, 2020 Magnetron‐based marine radar technology is mature, affordable, reliable, and very effective for maritime safety applications. Commercial systems may be procured at a modest cost as compared to fully coherent solid‐state systems. Magnetron oscillators inherently generate random phase signals.
