Abstract
1. Способ измерения радиолокационной отражаемости облачной среды, включающий радиолокационное зондирование облака на заданной длине волны, прием отраженного сигнала от локальной исследуемой ее области и отображение его на экране радара в виде огибающей, с последующей некогерентной обработкой данного сигнала путем измерения максимальной ее амплитуды (ZR) и расстояния (R) до этой амплитуды, и определение по данным проведенных измерений максимальной дальности аппаратурного контакта (Rmax.1) и максимальной интенсивности сигнала (Zmax.1), отличающийся тем, что дополнительно определяют максимальную дальность аппаратурного контакта (Rмах.2) путем когерентной обработки сигнала, затем определяют корректирующий множитель (К) как отношение величины Rmax.1 к Rmax.2, и геометрический путь (Rmax.г), соответствующий максимальной дальности аппаратурного контакта (Rмах.1), по формуле ! Rmax.г=K·Rmax.1, ! после чего определяют радиолокационную отражаемость по формуле ! ! где Сλ - постоянная радара. ! 2.

Способ измерения радиолокационной отражаемости облачной среды по п.1, отличающийся тем, что когерентную обработку сигнала осуществляют путем относительного перемещения локальной исследуемой области по оси дальности, для чего на приемном конце радара вводят ступень затухания энергетического потенциала радара (ΔZ), имитируя таким образом перемещение локальной исследуемой области по оси дальности, затем с экрана радара определяют проекцию огибающей эхо-сигнала на да1. A method of measuring the radar reflectivity of a cloud medium, including radar sounding of a cloud at a given wavelength, receiving a reflected signal from its local area of interest and displaying it on the radar screen as an envelope, followed by incoherent processing of this signal by measuring its maximum amplitude (ZR) and the distance (R) to this amplitude, and the determination according to the measurements taken of the maximum range of the instrument contact (Rmax.1) and the maximum signal intensity (Zmax.1), distinguishing Take advantage of the fact that you additionally determine the maximum range of the hardware contact (Rmax.2) by coherent signal processing, then determine the correction factor (K) as the ratio of Rmax.1 to Rmax.2, and the geometric path (Rmax.g) corresponding to the maximum range hardware contact (Rmax. 1) according to the formula! Rmax.r = KRmax.1,! then determine the radar reflectivity by the formula! ! where Cλ is the radar constant. ! 2. The method of measuring radar reflectivity of a cloud medium according to claim 1, characterized in that the maximum range of the hardware contact (Rmax.1) is determined by the formula! Rmax. 1 = R · 100.1 · Z R.! 3. The method for measuring the radar reflectivity of a cloud medium according to claim 1, characterized in that the signal is coherently processed by relative displacement of the local area of interest along the range axis, for which a step of attenuation of the radar energy potential (ΔZ) is introduced at the receiving end of the radar, thereby simulating moving the local area of interest along the range axis, then the projection of the echo envelope on yes is determined from the radar screen
