航管雷达选用两坐标体制,能够提供空中目标的距离和方位信息,不具备测高能力。文中结合航管雷达高低波束空域覆盖设计,提出高低波束联合测角方法,通过分析超余割平方高低波束交叠区域的功率曲线,给出系统高低波束设计准则和测高准则,可有效实现航管两坐标雷达进行测高,本文还分析测高区间和测高精度,具有较高的工程价值。

Air traffic control radar normally chooses 2D-radar system; it can provide information about distance and azimuth of the airborne target, but lack of altitude information. Based on two-beam system design, the united-beam height-finding method is provided in this paper. It not only provides principles of beam design and altitude measuring, but also gives altitude measuring area and accuracy of measurement. Simulation results show reference value in engineering application.
