摘要:针对原雷达高度表灵敏度测试效率低下的问题, 提出了一种基于二分法的雷达高度表灵敏度测试新方法。首先阐述了A-037雷达高度表测高原理、原雷达高度表灵敏度测试方法及二分法原理, 针对原灵敏度测试方法测试效率低下的问题, 提出了应用二分法来测量雷达高度表灵敏度的优化测试方法。该测试方法应用二分法首先快速确定灵敏度区间, 然后再以小步进梯度进行灵敏度精确测量, 在保证测试精度的基础上大大提高了测试效率。

Abstract: As the traditional approach of radar altimeter sensitivity testing was inefficient, an optimized approach of radar altimeter sensitivity testing using dichotomy method is proposed. This paper described A-037 radar altimeter working principle, the method to test sensitivity and the principle of dichotomy method, and then the optimized approach of radar altimeter sensitivity testing using dichotomy method is proposed aiming the inefficiency of radar altimeter sensitivity testing. Using the optimized testing approach, the cursory altimeter sensitivity is quickly detected, and then the precise altimeter sensitivity, which is more efficient while the testing precise of the sensitivity is the same.
Keywords: dichotomy method; radar altimeter; sensitivity; ATS
