| Abstract(in English) | Space debris are regarded as a space environment problem now, so that it is important to investigate their distributions and orbits. In this paper, we propose a signal detection and orbit estimation algorithms for KSGC radar located at Kamisaibara, Okayama Pref. in Japan. We approximate the motion of space debris as uniform motion within a short time, and improve the Signal to Noise-Ratio with a coherent integration. This method also improves the orbit estimation accuracy. The proposed method utilizes the quasi-periodicity of the evaluation function in order to effectively estimate the orbit. We applied the proposed method to the real data observed by KSGC radar. We show that our method can estimate the orbit with the errors of 89m for the range and 21m/s for the Doppler velocity, respectively. |
