解釋
寬帶干擾-
The fourth section studies the modeling of broad band blocking jamming and coherent jamming, and analyses the principal of coherent jamming and the factors of influencing the jamming effect is provided. the performance of pulse doppler radar seeker is simulated when certain jamming methods is exerted. a pulse doppler radar seeker simulation system is established, by using the simulation system the performance of pulse doppler radar seeker is evaluated when jammed
第四部分研究了寬帶阻塞式干擾和相干干擾的建模問題，並分析了相干干擾作用原理，給出了影響干擾效果的主要因素及次要因素，模擬了脈沖多普勒雷達導引頭在寬帶噪聲干擾情況下的截獲和跟蹤性能，模擬了相干干擾對脈沖多普勒雷達導引頭跟蹤性能的干擾效果。 -
This is by two reasons : the first, as the development of military communication technologies, it transit from digital to software implementation, intelligence, broad band implementation and network implementation. many new technologies such as adaptive frequency hopping, burst communication, broadband modulation and complex coding accelerate the research about pertinence algorithms of signal sense and signal processing. the second, three hotspots of modern signal processing - spectrum estimation, high - order statistics ( hos ) and time - frequency analysis theory become more and more consummately and being used in communication jamming and anti - jamming field
應用於軍事通信對抗的信號處理理論發展非常迅速，這得益於兩個方面的動力：其一，軍事通信的技術和手段不斷更新，在數字化的基礎上逐步走向軟體化、智能化、寬帶化和網路化，出現了自適應跳頻、突發通信、寬帶調制和復雜編碼等新的實用技術，推動了具有很強針對性的信號偵測和處理領域的演算法研究；其二，現代信號處理的三大熱點? ?譜估計、高階統計量方法、時頻分析的理論和技術日臻完善，並逐漸應用於通信對抗領域。
