The task of transformation of amplitude probability distribution of atmospheric radio noise from one bandwidth to another is given. The aim is to develop a fully automated algorithm for the transformation of distribution function for atmospheric radio noise from one lane to another. Transformation characteristics of atmospheric noise in the band are defined by temporal and amplitude scales of response functions of intermediate frequency receiver on a single pulse. Increase of receiver bandwidth leads to the fact that impulse response becomes shorter in time and higher in amplitude, i.e. if you change the bandwidth then the pulse shape of the response is changed so that the area under the curve always remains constant. In the case where the strip increases ω times, the scale of voltage impulse response is multiplied by the conversion factor of ω strip, and scale of the pulse duration divided by it. From this it follows that the amplitude probability distribution of atmospheric radio noise depends on transformation ratio. Also practical recommendations on the use of the algorithm are presented.
