中文摘要：
根据雷达一般成像原理,基于散射点模型讨论了目标旋转纵向位移及由此引起的散射点相位差的变化关系。通过数值计算详细分析了目标表面散射点雷达回波功率散射特性及相位随旋转角的变化特征。利用散射点模型讨论目标表面面元散射回波相位随目标姿态旋转角变化特征对开展全尺寸复杂目标雷达距离高分辨或者距离多普勒成像有一定的意义。
英文摘要：
According to the principle of the radar imaging, it is discussed the relations of the scattering points between the length direction＇ s displacements and the phase separation based on the scattering point model. And then, numerical methods are be utilized to calculate the echo power scattering characteristics and phase angle of scattering points on the surface of the target change with the rotation angle is analyzed in detail. It is great significance for research the radar high range resolution and range Doppler image of the whole dimensional targets by these works of the radar echo scattering characteristics based on the scattering point model.
