    Detection of Space Debris by means of Atmospheric radar
    (Addis Ababa University, 2006-06) Wamisho, Adila; Damtie, Baylie (PhD)
    Space debris, which are resulted from space activities among other things, are potentialproblems for the on going space science and development of space technology. A few alternatives in measuring, detecting, tracking and imaging space debris are there. Atmospheric signals contain signals scattered from space debris on top of signals scattered from the atmosphere. This thesis investigates how one can use atmospheric radar to detect space debris. The investigation is carried out by modelling the transmitted signal, the scattered signal for space debris in the presence of noise and also the impulse response of the receiver. We assume that the noise is white noise and for optimal detection we have employed matched filter at the receiver out put. The result shows that space debris can be easily detection by means of atmospheric radar
