Abstract : The PRecision Integrator for Meteorological Echoes (PRIME) is a versatile range-gated, analog integrator used to estimate the mean reflectivity of the radar returns from clouds and storms. A Log-IF Amplifier converts the returns ao the logarithm of the signal amplitude. The range resolution is selectable in seven steps from 0.05 to 0.8 statute mile, with a variable start of range. Contiguous range integration is also included in the same seven steps. The time of integration in all range elements is continuously variable from 5 to 500 msec by a single control. In addition to reflectivity, the output may represent other significant meteorological parameters at the operator's choice. The PRIME equipment has a dynamic range of 80 db. PRIME will operate with any conventional radar having PRF's from 200 to 5000 pps and pulse widths from 0.5 to 6 micro sec. (Author)
