Range estimator for laser fuses by methods of matched filters
Keywords:
Laser fuses, Poisson distribution, Cramer-Rao lower bound, Range estimationAbstract
Applying the technology of laser pulses to proximity fuses is considered more and more nowadays. The various noise sources can be modeled to derive limits on the precision of range measurements on the optical receiver. This paper examines several different matched filters to estimate the range measurements by the methods of cross-correlation. Noise sources in system is modeled using the Poisson distribution. The results of the simulation show that the most effective matched filter in range estimation is the square root filter.
