一种红外成像导引头探测视场实时扩展算法
Improved Method for IR-guided Weapons to Enlarge Field of View
摘要
Abstract
Owing to comparatively small working distances,IR-guided weapons are usually used in either terminal air defense or complex guided weapons.Radar/IR and INS/IR composites have recently gained popularity as tactical weapons.Reliable switching to the infrared mode with low guide precision is an important technique in composite seekers,making scan-technique and view-compound obligatory approaches for reliable handover.Based on the characteristics of the diminutive coordinator,this study designs a quick-scan technique,integrating into the INS assembly arithmetic-based image characteristics.To address the anterior error of complex images,compound arithmetic based on the Kalman filter is designed,combining INS communication with image characteristics.Finally,through simulations,the method was demonstrated to effectively eliminate accumulated errors.High-quality image stitching can also be achieved in extremely specific scenarios.This method yields a larger infrared detection field of view.关键词
