某型空中靶标雷达反射特性增强技术研究

Research on Radar Reflection Characteristics Enhancement Technique of Target Drone Character

针对某型空中靶标雷达反射特性与真实直升机差别较大的问题,提出了采用无源增强技术实现空中靶标雷达反射特性增强的方法。利用FEKO软件计算了某型空中雷达反射截面积,并利用无源增强技术对靶标减速板、垂尾、平尾等部位进行了雷达反射特性增强。计算结果表明,靶标雷达反射特性由-3.18 d B增加至9.47 d B,接近真实直升机的雷达反射特性(8.2 d B)。该方法在某型雷达侦察装备鉴定试验中得到应用,验证了该方法的有效性。

Aiming at the problem that the radar reflection characteristic of a certain air target is quite different from that of the real helicopter,the passive enhancement technology is applied to enhance the radar target reflection characteristics. Radar reflection area air was calculated by FEKO software and using the technology of passive enhancement target deceleration plate tail,tail and other parts for enhanced radar reflection characteristics. The target radat characteristic is increased from-3. 18 d B to 9. 47 d B,which is close to the radar reflection characteristic of real helicopter（ 8. 2 d B）,and has been applied in a radar reconnaissance equipment qualification test,which verifies the effectiveness of the method.
