摘　　要：以再入段的弹载雷达导引头为对象,研究其高速飞行模式下的点目标回波特性。利用三角剖分的Lawson算法,将数字高程地形分为若干三角形散射网格进行仿真,采用功率叠加的原理建立了复杂地形条件下的单脉冲线性调频雷达在导弹再入段的测高回波模型;利用BROWN提出的粗糙表面平均脉冲响应模型进行同等条件下的仿真,仿真结果验证了所提回波模型的适用性。The missile radar seeker in reentry section was taken as the research object for studying the point target echo model of it in the reentry high-speed flight mode. Based on the principle of Delaunay triangulation, the digital elevation terrain was divided into a number of triangular scatter grids by the interpolation algorithm of Lawson. After that, the altimeter echo model of the single pulse chirp signal radar under complex terrain in the reentry section of missile was established by using the principle of power superposition. And the rough surface average impulse response model proposed by BROWN was used to carry out simulation under the same condition, which verified the applicability of the echo model proposed in this paper.
