  • 摘要: 該文針對(duì)中段進(jìn)動(dòng)目標(biāo)平動(dòng)補(bǔ)償問(wèn)題，分析了中段目標(biāo)平動(dòng)及進(jìn)動(dòng)的運(yùn)動(dòng)特性，指出中段目標(biāo)進(jìn)動(dòng)具有軸對(duì)稱性，并利用這一特性提出一種基于對(duì)稱共軛相乘的進(jìn)動(dòng)目標(biāo)平動(dòng)參數(shù)估計(jì)方法。該方法通過(guò)對(duì)稱數(shù)據(jù)的共軛相乘處理消除微動(dòng)的影響，僅保留平動(dòng)參數(shù)信息，然后根據(jù)共軛相乘后數(shù)據(jù)傅里葉變換的峰值信息估計(jì)平動(dòng)參數(shù)，并基于所估計(jì)平動(dòng)參數(shù)實(shí)現(xiàn)了中段進(jìn)動(dòng)目標(biāo)平動(dòng)的高精度補(bǔ)償。仿真結(jié)果驗(yàn)證了所提算法的有效性。
    Abstract: To compensate the translation motion of precession ballistic targets, the characters of translation and precession are analyzed and it is found out that the precession has the center symmetry character. Using this character, a method based on conjugate multiplication of center symmetry data is proposed to estimate the translation motion of precession ballistic target. The precession motion is canceled out due to the conjugate multiplication and the translation motion parameters can be estimated by the spectral peak position of the conjugate multiplied signal. Therefore, the translation motion can be compensated based on the estimated translation motion parameters. Simulation results verify the validity of the proposed algorithm.
