距离高分辨测高技术

A Technique of Applying High-range-resolution to Height Finding

为了提高米波雷达低空探测性能,本文讨论步进频率体制下,单脉冲测角的米波雷达测高方法。首先利用步进频率信号的距离高分辨特性,得到回波的一维距离像,再对其进行前沿跟踪和单脉冲测角,进而得到目标的真实高度。仿真结果表明此种方法适用于对超低空目标的探测。

A new method for height finding using monopulse measurement based on stepped-frequency system is discussed in this paper for enhancing low-altitude detection of metric-wave radar. The stepped- frequency signal, which has the merit of high-range resolution, is adopted to acquire the high range resolution profile of the echoes, which are followed by front edge tracking and monopulse angle measuring, and then the accurate height is received. The simulation shows the effectiveness of the new method for the super low-altitude target detection.
