摘　　要：针对面元分解等方法在宽波束激光引信探测掠海目标时存在的问题,对已有激光散射模型进行改进,提出了考虑脉冲被不同面元散射的往返时间不同的因素的宽波束近场散射模型,并给出了散射接收功率的计算方法。分析表明,宽光束激光引信海面散射模型更符合实际情况,并且也为激光引信利用降低脉冲宽度的方法来进行目标识别和抗海杂波干扰提供了理论依据。In order to overcome the shortcoming of the wide-beam laser fuze detecting sea-skimming targets based on random facet,a near-field scattering model of laser fuze is put forward taking account of the factor that the round trip time of laser pulse differs as the pulse is scattered by different facet. A calculation method for the received scattering power is also given. The analysis shows that the proposed sea-surface scattering model of wide-beam laser fuze accords better with the situation and provides theoretical basis for target recognition and anti-sea clutter jamming by reducing the pulse width.
