摘　　要：介绍了影响海面后向散射系数和反射系数的各项因素,给出了雷达波束有效照射面积与入射余角、弹目距离、雷达脉宽和波束宽度在各种不同情况下的关系式,讨论了海杂波和多路径效应对雷达导引头工作性能的不良影响并提出了解决问题的若干对策.All factors affecting rearward scattering coefficient and reflection coefficient at sea surface are introduced. The equations of effective illumination area of radar wave related to incidence angle, distance between missile and target, radar pulse width and beam width under various conditions are given. The influences of sea clutter and multi-path effect on the radar seeker are discussed, and some advices are presented to solve the problem.
