An empirical analysis was performed on data for 2000 sporadic meteors. A bimodal log-normal equation was found for unaccelerated velocity distribution, by empirical curve fitting to match observed velocity distributions for meteoroids within 10 ranges of mass with due regard to failure of observation of faint meteors. An exponent of -1.34 was confirmed in the equation for cumulative influx rate of meteoroids relative to mass. An exponent of -3.87 was established for meteoroid velocity relative to Earth's atmosphere as used in an earlier weighting factor for correction of biasing effects of velocity and mass. Earlier theoretical results were closely approximated.

A statistical analysis was performed with use of Smithsonian Astrophysical Observatory's data on photographic meteors with use of weighting factors developed at Lewis Research Center for correction of various biases involved in meteor photography. The analysis used an armor damage criterion supplied by Ames Research Center. Although the analysis was restricted to Earth's orbit about Sun, implications are discussed regarding total population of meteoroids throughout the solar system. In Earth's orbit about the Sun, advantage was found for cylindrical armor extending in the solar direction and a plane sheet alined normal to apex of Earth movement.
