Development of radar to measure sea ice merits prize nomination

Research began with sea ice, for which field experiments were conducted to determine the optimum shape of the sounding signal. An original method was proposed which makes it possible to overcome the contradiction between the permissible value of radio-wave attenuation in sea ice and the possibility of distinguishing the top and bottom surfaces of ice cover separately. Onboard aircraft apparatus which was developed has begun to be used extensively for ice reconnaissance in various regions of the Arctic and on inland bodies of water of our country. The schematic concept for the method of receiving and processing signals was worked out, and an aircraft instrument for remote measurement of the thickness of sea ice was developed. The new remote measuring method was developed into ice reconnaissance and aerial surveying for ice-measurement purposes.
