  2. Some valuable conclusions are summarized by theoretical analysis and simulation experiments : from the side of signal processing, pulse jamming can be deleted by the method of time - domain sliding window accumulation and can be restored by interpolative prediction. ; gauss white nose can be attenuated while jamming disperse point - target by the method of time - frequency analysis in time - frequency domain. ; radio frequency noise jamming can be deleted by the method of average range frequency spectrum and notching in frequency domain

    通過大量的理論分析和模擬實驗，得到了一批具有一定價值的結論：從信號處理的角度出發，對于脈沖式干擾，能夠運用時域滑動窗口積累的方法去掉，並且通過預測插值得到較好的恢復；對于高斯白噪聲干擾，在時頻變換域內應用時頻分析方法可減小其對分散點目標的干擾；對于射頻噪聲，通過平均距離頻頻法和頻域陷波的方法可以去掉；從改變合成孔徑雷達系統角度出發，類似雙基地雷達能夠避免各種干擾，對發射信號進行調幅，調相以及改變調頻斜率都是較好的抗干擾方法。
