The Research Of Space Target Surveillance Radar's System Design In View Of Stk

The quantities of space debris are increased day by day with the human space activities increasing. Space debris are castoff abandoned by human space activities, they are the dominating pollutant. Exploration of space debris is necessary to ensure space activities safety, such as manned space, lunar exploration and application of satellite, etc.Firstly, space target surveillance system is summarized, and Surveillance Equipments are introduced. Then space target environment are analyzed, including scatter cross section, cycle distribution, inclination distribution, eccentricity distribution, perigee altitude, apogee altitude, and Semi-major axis. The design method of space target surveillance radar is studied, and a new design method is presented analyzing from several aspects, such as the choice of frequency band and polarization mode, radar scale, inclination of array and multi-objective ability. The method of space target surveillance radar of performance analyze is presented. STK simulation software and modules are introduced. The ability of searching and tracking are simulated based on STK. The process of simulation is analyzed in detail, and the implementation method is given.
