Pulse compression systems for use with meteorological radars


  • G. L. Austin


The theory of pulse compression systems for extended precipitation targets is reviewed referring specifically to a 13:1 phase-coded compression system currently in use. The expected loss in sensitivity of a factor b, the compression ratio, is obtained compared with b2, obtained by transmitting shorter pulses. The effects of the range sidelobes in smoothing out steep gradients of reflectivity are examined. It is concluded that they are serious but not prohibitive.
