天线差斜率对测量雷达测角精度的影响
Normalized Difference Slope in Precision Tracking Radar Angle Accuracy
摘要
Abstract
For precision tracking radar ,system power and precision are two key parameters for the antenna design. In the antenna design, system power is mainly supported by the antenna sum gain, and measurement precision of radar antenna is supported by normalized difference slope, whereby the antenna normalized difference slope is the important factor affecting accuracy of angular measurement of radar. The difference slope definition and difference slope influence on system accuracy is elaborated emphatically in this article. Then, combining with the actual situation of radar, influence of five hom feed difference slope on system accuracy is analysed. Last, measures to optimize the feed are proposed, and system random error of radar angle which is optimized is tested and it can meet the design requirements.关键词
