Theoretical analyses show that it is possible to measure the space debris with radius greater than 0. 5m in the altitude range between 200km and 1200km using meteor radar developed by CSAO.
According to the basic characters of Propagation of radio waves in several typical scatter communications, this paper establishes random process probability model by mathematical analytical method and deduces theoretical model of multipath spread probability distribution of Tropospheric Scatter Communication, Meteoric Trail Scatter Communication and Ionospheric Scatter Communication
The collision of comet Shoemaker-Levy 9 with Jupiter is essentially a particular meteoric physical problem during the cometary fragments into Jupiter's atmosphere. In this paper, profile formula of their velocity, mass loss, luminosity, electron line density and energy release rate on height are derived from fundamental equations of meteoric physics.

The effective temperatures of typical iron meteors at 90—90km in altitude with different initial geocentric velocities and particle number densities of main components with an initial velocity of 72km/s were calculated based on Sparrow's theory. UV radiation within the 240—400nm band of the wake was simulated by using the cloudy code,and relative intensities of several expected strong emission lines were predicted.
The larger trails can be seen with the naked eye, but even the smaller meteors down to 15th magnitude,which are more common,The left trails that provide radar targets.
The paper is devoted to studying the motion of meteor bodies with mass outflow in a planet's atmosphere, taking into account the non-isothermal character of the latter.
"Falling Star" includes a range of automated procedures for the identification of frame stars with star catalogues, search of movable meteor-like objects inside frame, calculation of equatorial coordinates and photometry.
