摘要
电离层杂波是制约高频海态监测雷达探测性能的因素之一,为进一步深入分析电离层杂波特性及成因,提出了对电离层探测信息的杂波分析方法.该方法在传统利用雷达回波进行分析的基础上,引入电离层垂直探测信息,综合应用电波传播理论,对电离层杂波进行分析.给出了常规F层杂波和出现概率较高的Es层强杂波、"微笑"型杂波的特性及产生机理.通过仿真分析和试验数据验证,证明上述分析方法和结果有效,可为电离层杂波抑制提供支撑.
The performance of HF surface wave radar(HFSWR)is limited by ionospheric clutter.In order to get characteristics and causes of ionospheric clutter,a method based on ionospheric sound is proposed.Based on traditional method which uses radar echo,ionosoude is introduced into HFSWR and the theory of wave propagation is application to analyze clutter.Characteristics and causes of ionospheric F layer clutter,Es layer strong clutter and a kind of 'smile' type clutter are given by the analysis.Simulation and experimental show its effectiveness,and it can be useful in ionospheric clutter suppression.
