從破壞機(jī)理和損傷閾值方面分析了光電探測(cè)器的干擾機(jī)理。給出了激光干擾概率模型，提出自適應(yīng)干擾和時(shí)域均勻干擾兩種干擾模式，對(duì)兩種不同干擾方式下掃描成像設(shè)備的干擾概率進(jìn)行了理論計(jì)算并得出了試驗(yàn)結(jié)果，驗(yàn)證了偵察-干擾工作模式的有效性，證明了激光自適應(yīng)干擾是光電對(duì)抗中的首選干擾方式。

Abstract The interfering mechanism on the photoelectric detector is analyzed in damage mechanism and jamming threshold. The model of laser interfering probability is given. The self-adaptive interference and even time-domain interference are provided and the theoretic probability of two different types of interference on the IR scanning imaging systems is calculated. The effectiveness of surveillance and interference mode is proved in the experimental results. It is also proved that the laser self-adaptive interference is the first choice in different types of optoelectronic countermeasures.
