WebCoherent scatter radar provides a unique perspective of Joule heating by accessing both very small scales, but also providing spatial observations over mesoscales. However, investigations specifically focused on Joule heating from coherent radar observations are relatively limited compared to incoherent scatter radar. WebX-Band Furuno DRS25A Marine Radar is magnetron oscillator based, and inherently non-coherent, operating at 9410 ± 30 MHz with a selectable signal bandwidth of between 1.25 to 12.5 MHz. A low duty ...
