Calculations are presented of the effect of pulse-pair correlation on the detection statistics of alarm systems using differential absorption lidar (DIAL) for the remote sensing of toxic gases. This experimentally observed correlation is found to have a significant beneficial effect on the performance of such systems. The calculations are performed for both coherent- and direct-detection DIAL systems using a statistical detection model that assumes a bivariate normal distribution for the on- and off-resonance returns.
