Research on Detection Technology of Infrared Missile Target Signal Based on Four Element Detector
摘要
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(Rdis 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.关键词
