| 摘 要： | 通过对反辐射炮弹概念的论述,分析了反辐射炮弹的趋势;采用理论分析和仿真验证相结合的方法,得出了比相误差与测向误差之间的关系,指出了炮弹反辐射视向角误差组成,并据此提出了基于EMD的方法对弹上测向进行预处理来提高测向精度。仿真结果表明该信号预处理方法能提高视向精度,并具有很好的抗干扰能力。

| Abstract: | The development trends of anti-radiation projectile(ARP)were analyzed by discussing its concept.The relation between the direction-finding(DF) accuracy and the relative phase error was studied theoretically and analogically,and the composition of ARP DF error was pointed out.A signal preprocessing method based on EMD(empirical mode decomposition) was put forward to improve DF accuracy of ARP.The simulation results show that the preprocessing method is useful and robust. |
