摘　　要：米波天线的波长较长,在天线俯仰面孔径受限的场合,多波束测高等常规方法无法应用,不能实现高度测量。文章研究分析了利用海面多径信号测高的原理及算法,并经过仿真试验对探测空域进行了测高精度分析,最后给出了雷达测高概率和精度等高线分布。试验结果证明了该算法的有效性。The capability of height finding is demanded for meter-wave radar in modem war, but the wavelengh of meter-wave radar is rather long. And the usual height finding method such as Height Finding Method based on Multi-beam cannot be used when the antenna aperture is limited in elevation direction. This will cause altitude measurement not to be realized. In this paper, a height finding method using the muhipath signal over the sea surface is simulated, and the precision distribution of altitude measurement in detecting airspace is analyzed. Finally, the probability and precision contour lines distributions are provided. The result shows that the method is feasible.
