The analysis of a general pulsed laser rangefinder was applied to the submunition guidance problem using a computer simulation to optimize the performance. The simulation developed herein is valid for a wide variety of similar applications, requiring only modification of the system parameters such as raw laser power, field of view, etc. The proposed preamplifier was tested and found to have adequate bandwidth, and the constant fraction threshold detector performance was validated over a 40 dB dynamic range. It should be mentioned here that the dynamic-range-induced errors may be further reduced by limiting the amount of dynamic range the receiver sees.
