有源干擾的能量在SAR圖像中分布的研究
The Distribution of the Jamming Energy in SAR Image
-
摘要: 該文研究了對合成孔徑雷達干擾中的能量問題, 提出了干擾能量的等同原則。指出如果雷達接收到相同能量的干擾，那么經(jīng)成像處理后在雷達圖像中的總干擾能量相同，不同相關(guān)性的干擾信號可以改變干擾能量在合成孔徑雷達圖像中的分布；這對選擇合適的干擾方法和研制干擾系統(tǒng)具有參考意義。此外，文中還推導了合成孔徑雷達干擾功率的計算公式。

Abstract: This paper is about energy problem in SAR jamming. A new concept of Jamming Energy Equivalence (JEE) is presented here. The concept implies that SAR warfare is still power warfare, though SAR is interference radar. This paper indicates that different jamming methods only lead to different distribution of the jamming energy in SAR image, which is useful to the choice of jamming method and the building of jamming system. In addition, this paper gives the jamming equation of SAR. -
