The authors present the results of experimental studies and appropriate model calculations of the characteristics of the thermal radiation field of a water surface in the shf range - the average values of emittance, the degree of polarization, and the space-time variations of radiation intensity. Measurements made at a coastal point on the 0.8, 1.35, 1.6, 3.2, and 3.37-cm bands from on board an aircraft on the 3-cm band, and aboard the Kosmos-243 satellite on the 0.8, 1.35, 3.4, and 8.5-cm bands made it possible to obtain dependences of the radiation characteristics on the force of sea swells. Observations from the coastal region and aboard the aircraft were performed with wind speeds to 5-7.5 ms, those from the Kosmos-243 - to 15-20 ms.
