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7.86R_d^2(R_d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。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 Rd 2(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.
