Efficient search strategies for a low earth orbit surveillance radar

Abstract

This work describes efficient search strategies for an LEO surveillance Radar. A short introduction on space debris and space situational awareness is given. Basics on the orbits of satellite objects are then discussed. Based on these an optimized surveillance method and search area for the Radar is chosen. Finally it is discussed how different methods like sequentially searching in a near and far range sector or an angle-dependent waveform design lead to a reduced necessary power aperture product and thus to lower hardware costs.
