Question: A passive microwave radiometer operating at 37 GHz has an effective area of 0.3 m 2 , and can detect a change of 0.9 K

A passive microwave radiometer operating at 37 GHz has an effective area of 0.3 m², and can detect a change of 0.9 K in its antenna temperature. It is operated from an altitude of 800 km to observe a single ice floe (whose brightness temperature is 253 K) surrounded by water (brightness temperature 119 K). Calculate the area of the smallest detectable floe.
