Show During the 1968-69 operational season at the Park Range location, a Nike Ajax radar at Mt. Harris and a GPG-1 radar at Lodwick were used to ob~ tain quantitative profile estimates of precipitation over the target area. This was accomplished using a variation of the well known radar range equation which is given by Battan (1960) as: p P where Pt = = r CJ r t + G2 A2 Rt = received power in Watts. = Antenna Gain ThE shiJ Wave length of radar in cm. 2 Range to the observed target in cm. wh The variation used for weather scatterers is accomplished according to Atlas and Mossop (1960) by substituting for a = NV (2) Here Vis the pu l se volume given by Handman and Davis (1964) as: V e f/J cm Sub1 Target backscatter cross section in cm = (1) and that peak transmitted power in Watts.
