摘　　要：通过理论分析,指出可用于激光半主动寻的制导的激光编码方式主要有脉冲间隔调制(PIM)和脉冲宽度调制(PWM)。通过分析和研究现有的国内外许多激光编码及其特点,提出了一种PIM编码与PWM编码混编的新型编码思想,并给出了具体的编码方法。最后给出了激光编码的发展趋势。On the base of laser modulation concept, only two modes of laser modulation, pulse interval modulation （PIM） and pulse width modulation （PWM）, which can be used in laser semi-active guidance, was pointed out by theory analyses. By analyzing and studying the characteristic of many laser codes at home and abroad, and a new encoding method combining PIM and PWM, and the embodiment of its realizing method was pat forward. It provided with the developing trend of laser encoding in the end.
