Use of radar with frequency modulation for studying atmospheric boundary layer

Measurements of the vertical component of the motion of a disperse medium are used to show that a radar with linear frequency modulation (LFM) can be effectively used as a Doppler radar in studies of the atmospheric boundary layer. Spectral responses due to rain and nonuniformities of the air refractive index are included. Among the advantages of the radar with LFM are high spatial resolution of 1 m as compared to 150 to 75 m for pulsed coherent radars; smaller physical dimensions, complexity, and cost of the instrument; and a smaller minimal distance R(min). It is reported that the first implementation of the radar with LFM demonstrated the ability to retrieve data from altitudes of 20 m over the entire distance range at a power of 10 W.
