摘要: 該文總結(jié)了彈道導(dǎo)彈目標(biāo)雷達(dá)識(shí)別的研究現(xiàn)狀,引入微進(jìn)動(dòng)和微RCS的概念,推導(dǎo)了進(jìn)動(dòng)錐體目標(biāo)對(duì)雷達(dá)波的姿態(tài)角計(jì)算公式,分析了微RCS和姿態(tài)角的關(guān)系,使用進(jìn)動(dòng)錐體目標(biāo)的微RCS序列估計(jì)目標(biāo)進(jìn)動(dòng)參數(shù)和慣量比。以慣量比為特征,提出了識(shí)別彈頭和誘餌的方法。最后給出了仿真結(jié)果。

Abstract: In this paper, the development of radar identification of ballistic missile warhead is summarized. Conceptions of micro-precession and micro-RCS are introduced. The aspect angle expression of a precession target is derived, and the relationship between micro-RCS and aspect angle is analyzed. Then the precession parameters and inertia ratio are estimated with micro-RCS. Inertia ratio is then used to discriminate warheads and decoys. Finally, a simulation result is provided.-
