红外导弹四元十字探测器视场四瓣梅花状 infrared missile four element and ten element cross detector the field of view four petal and plum shape

摘要

红外导弹目标信号探测场(视场)是红外导弹的重要指标, 基于某型导弹四元十字探测器光学结构与特殊性, 给出了四元十字探测器目标信号探测方法, 得到其探测场(视场)形状为四瓣梅花状, 探测场的视场面积为 7.86Rd2(Rd为探测器单元长度)。通过与圆锥扫描调制盘比较, 探测场(视场)面积为圆锥扫描调制盘 2倍, 等效半径为圆锥扫描调制盘 1.414倍, 通过与单元调制盘比较, 面积为单元调制盘 2.5倍, 等效半径为单元调制盘 1.6倍, 具有比圆锥扫描调制盘和单元调制盘更大的视场探测范围。

Abstract

The detection field of the target signal is an important index of the infrared missile. The structure particularity and the optical system particularity of the missile's four-element cross detector are analyzed. The target-signal detection method of a ten-element cross detector is presented. The shape of the probe field is four-plum, with the area of the probe being 7.86 Rd2(Rd is the length of the probe unit). In comparison with the conical-scanning modulation disk, the area and equivalent radius of the probe field are 2 times and 1.414 times those of the conical-scanning modulation disk, respectively. In comparison with one modulation disk, the area and equivalent radius of the probe field are 2.5 times and 1.6 times those of one modulation disk, respectively. This method facilitates a field of view larger than those of the conical-scanning modulation disk and one modulation disk.
