摘　　要：多窗口激光告警接收机结构形状直接决定其探测入射激光视场范围及方位角的分辨能力,提出了一种基于三角形窗口和梯形窗口组合使用的多窗口激光告警接收头设计方法,理论上分析了该种方法均匀分割探测视场空间的原理,并设计了基于6个三角型窗口和6个梯形窗口的半球形激光告警接收头.样机试验结果表明,该接收头可以将半球视场均匀分割为36个视场区,每个视场区均为俯仰角30°,方位角30°.The construction and shape of a multi-windows laser warning receiver determined its detecting ability of the field of view and resolution of the azimuth angle. A new design method of a laser warning receiver optic system was put forward with triangle windows and trapezoid windows in the paper. The working principle was proved from theory of uniformly segmenting the field of view, and a hemispherical laser warning receiving head was designed with six triangle windows and six trapezoid windows, and the experimental results show that the hemispherical field of view is segmented into 36 uniform areas with an pitch angle range 30° and an azimuth angle range 30°.
