The energy detection of multipulse returns from an optically rough target is considered. A Q-switched laser generates a number of precisely timed giant pulses during a single pumping period. The multipulse signal photoelectron statistics are shown to be negative binomial. The statistical detection performance of single and multipulse systems are compared over a wide range of noise levels. The multipulse rangefinder has a power advantage of from 15 dB to over 28 dB under the conditions considered.
