Metcalf (1997) has disagreed with this point. We note that one cannot determine from single polarization transmissions whether a backscatter effect is present or not, except possibly by examining the reflected power. No changes were detected in the co-polar circular polarization power at the time of lightning discharges, down to noise level of these signals (Chen, 1994). A definitive answer to this question requires the transmission of successive LHC and RHC signals (McCormick and Hendry, 1979).
