Analysis of the SNR for 3-D Rotating Sea Ship Detecting in Geosynchronous Synthetic Aperture Radar System

  • 摘要: 回波信號信噪比(SNR)是決定地球同步軌道合成孔徑雷達(GEOSAR)艦船目標檢測性能的關(guān)鍵指標。該文針對GEOSAR衛(wèi)星與艦船目標超遠作用距離導(dǎo)致的單脈沖回波低信噪比問題，具體分析了方位脈沖相干積累對艦船目標檢測信噪比的提升，以及信噪比提升受艦船目標3維轉(zhuǎn)動的影響，并通過實測數(shù)據(jù)處理和仿真實驗得出了相關(guān)結(jié)論。
    Abstract: Signal to Noise Ratio (SNR) of the echo is critical for the detecting performance of sea ship in GEOsynchronous Synthetic Aperture Radar (GEOSAR) system. To address the low SNR problem of single pulse echo due to ultra-long distance between the satellite and sea ship, specific analysis of the improved SNR with coherent integration and its suffering from 3-D rotations of sea ship is carried out in this paper, corresponding conclusions are drew through processing of simulating and real data.
