摘要
目前,在雷达干扰效果评估的相关研究中,大多将雷达探测目标的雷达截面积(RCS)设为常数.实际上,目标的RCS是起伏的,会影响干扰效果.基于此,论文中提出了一种基于RCS起伏模型的雷达干扰效果评估方法,通过理论分析得到了目标RCS起伏条件下的干信比概率密度函数模型,进而推导提出了目标RCS起伏条件下的有效干扰概率模型,并运用该模型对不同场景下的干扰效果进行了仿真评估,为干扰策略优化提供了有效支撑.
Abstract
Absrtact At present,in the research of radar jamming effect evaluation,RCS is usually set as a constant.However,the tar-get's RCS is fluctuating,which will affect the jamming effect.Based on this,a method of radar jamming effect evaluation based on RCS fluctuation model is proposed in this paper.First,the model of snr under the condition of RCS fluctuation is derived by theoreti-cal analysis.then,the model of effective jamming probability under the condition of RCS fluctuation is derived and used to evaluate the jamming effect in different scenarios,which provides effective support for jamming strategy optimization.
