Determining the distance range of electro-optical systems using Johnson criteria and expressing strategies to deal with concealment of targets

Detection of small targets is usually done using infrared equipment and thermal detectors, so calculating the range of these systems is of particular importance, so Johnson's expression is the most important goal of this project. Also, in order to get acquainted with various strategies for hiding targets, familiarity with infrared waves is of special importance and plays an important role in categorizing and selecting the appropriate tools to achieve the overall goal of the project, namely the detection of small bird targets. The implementation of visible and infrared concealment methods has made it even more difficult to identify these targets, so we will examine these methods and provide methods to overcome these difficulties.Detection of small targets is usually done using infrared equipment and thermal detectors, so calculating the range of these systems is of particular importance, so Johnson's expression is the most important goal of this project.
