A Robust RCS periodicity estimation algorithm for ballistic target;

After the characteristic of ballistic target recognition was analyzed, it was pointed that alleging decoys was a Neyman-Pearson decision in essence, which sought the least cost of recognition.

It is of great meaning to research the ballistic target recognition technique.

Summary of the 3D pose estimations for the space targets;

In order to detect spatial object effectively,the structure of laser active imaging system is described,and the radiation characteristic of spatial object and space circumstance is analyzed in detail.

This paper investigates the causes and origins of uncertainties in spatial objects and their classifications.

Based upon the fundamental concepts in rough set theory,this paper proposes rough set models to represent the uncertainties in position,attribute and topological relation of spatial objects.

The Real-time Simulation and Play-back of Space Targets IF Radar Echo;

In this paper,combined with the movement characteristics of three-axis stabilization secondary planet,spin stabilization secondary planet and space fraction,and in the basis of strong scattering center theory,the electromagnetism scattering model of space targets is established and the simulation results of space targets are given.

In space operational simulation virtual environment,space targets-satellites and space debris are in large quantities,and their orbits calculation affect the simulation speed directly.
