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

摘要

摘要: 回波信号信噪比(SNR)是决定地球同步轨道合成孔径雷达(GEOSAR)舰船目标检测性能的关键指标。该文针对GEOSAR卫星与舰船目标超远作用距离导致的单脉冲回波低信噪比问题，具体分析了方位脉冲相干积累对舰船目标检测信噪比的提升，以及信噪比提升受舰船目标3维转动的影响，并通过实测数据处理和仿真实验得出了相关结论。

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.
