ground echo 地面回波。

ground effect

Chapter 3 studies the false target jamming . jamming signal generation formula is proposed by the investigation of simultaneous ground echoes of two different point targets in radar beam . comprehensive research about the characteristics of jamming signal is made , and raw data is used in simulation 第三章對虛假圖像干擾進行了研究,通過對雷達波束內兩個不同的點目標在同一時刻的回波信號進行的分析比較,推導了干擾信號的生成公式,對干擾信號的特征作了詳細的分析,并結合實測數據做了仿真實驗。

Chapter 2 deals with the ground echo signal of sar , and establishes the signal models of static target and moving target 第二章研究了合成孔徑雷達回波信號,建立了靜止目標和運動目標的回波模型。
