摘要
对影响机载预警雷达测高精度的因素进行分类基础上,针对单脉冲雷达的测角方法,列出了影响机载预警雷达测高精度的主要因素。基于地/海杂波、大气折射、电波传播多径效应、载机平台运动和导航系统等因素,分析了对于机载预警雷达测高误差产生的机理,评估了多种因素对测高精度的影响程度,提出了在系统设计和补偿固定误差等方面提高雷达测高精度的建议。
This paper classifies the factors which have impacts on the altitude-measurement precision of airborne early warning radar,and introduces the main factors of impacting altitude-measurement precision of the monopulse system radar.Based on ground/sea clutter,atmospheric refraction,multipath effects and airplane movement effects,the altitude-measurement errors of the airborne early warning radar are analyzed.After evaluating the error levels in altitude-measurement precision caused by these factors,the suggestions in radar system design and fixed error compensation are given to improve altitude precision.
