摘　　要：脉冲多普勒引信海面回波仿真是根据无线电脉冲多普勒引信的探测特点和海面反射特性划分海面有效照射区域的等距离线,并由导弹飞行姿态和引信天线波束宽度确定海面有效照射区的等多普勒线。利用雷达方程进行建模仿真,对回波能量进行积分得到引信回波功率,对照射面元回波累加得到多普勒回波信号,从而为研究脉冲多普勒引信海面低空工作性能提供参考。The simulation of sea echo of pulse doppler fuze is the equal distance lines of dividing the sea surface effective radiation area,according to the detection characteristic of the pulse doppler radio fuze and the sea surface reflection characteristic. And the doppler isoline of sea surface effective radiatian area is determined by the missile flight pose and the fuze antenna irradiation wave width. Using the radar equation modeling,the echo energy is integrated to get the echo power,and the doppler echo is calculated by adding up the echo of surface elements. This provides a referene for researching the low sky working performance of the pulse doppler radio fuze.
