摘要: 紅外玫瑰線掃描亞成像目標(biāo)識(shí)別系統(tǒng)是當(dāng)今主要的最優(yōu)末制導(dǎo)系統(tǒng),但該類系統(tǒng)的成像空間分辨率較低,該文研究了玫瑰掃描參數(shù)最優(yōu)控制準(zhǔn)則,提出了掃描初始相位參數(shù)控制法,通過改變每幀的初始相位并進(jìn)行多幀掃描相圖重疊,高速高效地形成了高分辨率成像空間。DSP系統(tǒng)實(shí)驗(yàn)結(jié)果表明,該技術(shù)有效地提高了系統(tǒng)的成像空間分辨率。

Abstract: The subimaging target recognition system of infrared rosette scanning is the main optimal terminal guidance system, however, the resolution of the imaging space is not high. Based on the optimal controlling rule of scanning parameter, this paper proposes the phaseshift parameter controlling method which is performed through shifting the phase and overlaping the multi-frame phase diagrams. Thus, high resolution of imaging space under the condition of high speed, nice efficiency is achieved. The experimental results of DSP system show that this technology improves the image resolution of the system effectively. -
