摘要
针对雷达对抗中压制系数的多种定义容易混淆以及定量描述十分困难的问题,通过雷达接收机的简易模型,分析了每一种压制系数的特点及其相互之间的关系,推导出了绝对压制系数Ka与RSN的定量关系,并进一步分析了雷达抗干扰改善因子与压制系数的关系,找到了雷达对抗中定量准确描述压制系数的方法。通过计算与理论分析得出干扰有效时外部干扰信号能量与内部噪声信号能量的关系。
According to the easily confused problem of multiple definitions and the difficulty in quantitative describing of suppression coefficients in the field of radar countermeasure, the characteristics of every suppression coefficient and the relationship among them are analyzed by simplified model of radar receiver. The quantitative relation between the absolute suppression coefficient Ka and Rs~ is deducted, the relation between the radar anti-jamming improving factor and suppression coefficient is further analyzed, and the accurate quantitative description method of suppression coefficients in radar countermeasure is obtained. Finally, when jamming is effective, the relationship between external jamming signal energy and internal noise signal energy is derived by calculation and theoretic analysis.
