It is customary to censor signals in conventional weather radar using estimates of signal-to-noise ratio (SNR) and/or magnitude of autocorrelation coefficient at lag one. Dual-polarized weather radar provides a pair of highly correlated signals from the two orthogonally polarized returns. A novel censoring technique, previously proposed, sums powers, autocorrelations, and correlation between signals in the two channels and compares the sum to a threshold. In this paper an efficient procedure for calculating such a threshold is proposed.
