摘要
数据后处理雷达基于真假目标雷达回波距离和方位展宽特征差异实现抗干扰,传统的单点目标回波生成方法难以满足数据后处理雷达对抗技术的验证。定量分析真实目标雷达回波在距离和方位的展宽特征,并站在雷达对抗技术仿真验证角度提出一种基于距离扩展调制和方位扩展控制的逼真回波信号产生方法。经仿真验证表明,该方法产生的回波信号经雷达处理后具有逼近真实目标的展宽特征,对新体制雷达对抗技术仿真验证系统的设计具有参考意义。
Anti-jamming could be achieved by data post-processing radar based on the charac-teristic differences of range and azimuth extending between the true target echo and false target echo,and the validation of the jamming technology against data post-processing radar could not be satisfied by the traditional method of point target echo generation.The range and azimuth ex-tending characteristics of the true target echo is analyzed quantitatively,and then a high fidelity echo simulation method is presented based on range extending modulation and azimuth extending control,from the perspective of radar jamming technology validation.It is verified by simulation that the echo generated in this method is very similar to the true target echo after radar process-ing,and this method has very important reference significance to the design of the new radar jam-ming technology simulation and validation system.
