Four cases in north Atlantic for 2023 hurricane season and SAR observations over: (a) Hurricane Idalia acquired at 11:26 UTC on 28 August, 2023, onboard RCM-1, (b) Hurricane Franklin acquired at 10:21 UTC on 26 August, 2023, onboard Sentinel-1A, (c) Hurricane Lee acquired at 09:03 UTC on 7 September, 2023, onboard RCM-2, and (d) Hurricane Margot acquired at 08:28 UTC on 11 September, 2023, onboard RCM-1. The FFT (fast Fourier transform) peak results along the black lines are 20.0 km, 25.0 km, 20.0 km and 16.7 km respectively.
