Abstract:
A weather hazard detecting radar system for determining the presence of supercooled liquid water droplets, comprising:means for transmitting signals with a predetermined polarization; means for receiving said signals, as reflected by hydrometeors in the atmosphere, those received signals including those being co-polarized with respect to said transmitted signals as well as those being cross-polarized with respect to said transmitted signals, said receiving means including an antenna and means following said antenna for separating said co-polarized signals and said cross-polarized signals into separate channels; amplifier means, including means for inputting said co-polarized and cross-polarized signals from said separate channels and for converting said signals to a lower frequency, and further including an outputting means for said lower frequency signals; temperature sensing means having a signal output; processing means for inputting said lower frequency signals from said amplifier outputting means and said temperature sensing means output and for processing said signals according to a predetermined algorithm, said algorithm including means for determining the presence of supercooled liquid water droplets.
