有源干扰压制区计算模型研究

摘要

雷达干扰压制区域的绘制与计算是电子战辅助决策过程中必不可少的,如何合理地建立干扰压制区的计算模型十分重要。在对雷达探测理论计算和实际抗干扰措施分析的基础上,修正了干扰压制区的计算模型,通过计算支援干扰时进入检波器的干扰功率与热噪声功率的数值关系,比较采用原计算模型和修正后计算模型得到的干扰压制区域的大小,验证了该模型的合理性、有效性。%Drawing and calculation of radar jamming suppression area is a necessary part in the process of electronic warfare assistant decision-making.It is important to rationally establish the calculation model of jamming suppression range.Based on the analysis of theoretical calculation of radar detection and practical anti-jamming measures,this paper modifies the calculation model of jamming suppression area,by means of calculating the numerical relationship of thermal-noise power and jamming power that enters into the detector when support jamming accurs,compares the scopes of jamming suppression area using the original calculation model the modified model,verifies the validity and rationality of the modified model.
