摘要
采用HFSS软件SBR方法实现5型火箭全空域双频段RCS仿真,采用视线角转换实现测量RCS与仿真RCS序列的有效比对,分析了仿真误差产生的原因,提出了模型参数调整和实测数据修正相结合的雷达RCS修正方法,将火箭仿真精度从5 dB提高到2 dB,雷达识别能力得到有效提升。
In this paper,the HFSS software SBR method is used to realize the dual-band RCS simulation of type 5 rocket in the whole airspace,and the line of sight angle conversion is used to realize the effective comparison between the measured RCS and the simulation RCS sequence.The causes of simulation errors are analyzed,and a radar RCS correction method combining model parameter adjustment and measured data correction is proposed.The accuracy of rocket simulation is increased from 5 dB to 2 dB,and the radar identification ability is effectively improved.
