This thesis discusses the pulse doppler ( pd ) weather radar signal processing system including digital intermediate frequency ( if ) receiver, especially on the application of if sampling and digital demodulation technique in pd weather radar signal processing system, the influence of amplitude and phase unbalances of in - phase and quadrature channels on weather radar echo spectrum estimation, ground clutters elimination algorithms and a typical engineering realization scheme of pd weather radar signal processing system
本論文研究的是採用數字中頻接收技術的脈沖多普勒氣象雷達信號處理系統,重點研究了中頻采樣及數字解調技術在脈沖多普勒氣象雷達信號處理系統中的應用、正交雙通道幅相不平衡對氣象回波譜估計的影響、地雜波濾波演算法,以及脈沖多普勒氣象雷達信號處理系統的具體工程實現。Because the performance of analogue receiver is not good, the gain - and - phase errors of receivers are generated, which badly affected the image of sar
由於接收機模擬器件的非理想性和非穩定性,接收機對回波信號進行幅相調制,產生幅相誤差,影響合成孔徑雷達的成像結果。Based on the components of analogue receivers, all kinds of influences on the signal from all kinds of components are given, then the influences on the result of pulse compression from the quadrature demodulators is focused on
接著分析各個模擬接收機組件對回波信號產生的各種幅相誤差,這些誤差會對信號頻譜和脈壓結果產生影響,並重點分析正交解調幅相誤差對它們的影響。
