Lock-on range of infrared heat seeker missile

This study focuses on development of mathematical model of Infrared Signature from the first principles using MATLAB environment. The model is used for IR Signature studies and further adopted for aircraft susceptibility analysis with its computed Infrared Signature level (IRSL). The model is validated with the existing literature data of the IRSL from the engine parts of an Aircraft and thus finding the lock-on range from an Air to air missile. This paper reviews the steps to find the lock-on range, with particular focus on IR signature prediction for aerial platforms. In this investigation, the lock-on envelope is estimated in 1.9-2.9μm, 3-5μm and 8-12μm bands, considering various sources of IR signature from aircraft engine surfaces for aerial platforms. The developed model is important for further susceptibity studies of aerial platforms for survivability improvements related studies for any new design configurations and are an important factor of stealth technology.

“…An example of this type of system is the Russian SA-14 which entered in service in 1974 as an improved version of the SA-7b with better tracking and a wider aspect capability. It could track cooler targets at greater ranges and engage faster moving targets [10]. Also the SA-16, brought into service in 1981 was still based on the same CONSCAN IR seeker.…”

Since the 1950’s infrared (IR) guidance technologies have been increasingly used in various fields including scientific, industrial and military applications. Affording visibility despite light conditions, in military applications IR made possible night vision, as well as seeker systems intended to guide missiles autonomously to their targets. This article presents a historical overview of IR guidance and discusses to of its current applications in portable air defense systems.

“…One method of locking the missile system in TERCOM is using infrared. As developed by Ab-Rahman and Mazen R., the locking system using the infrared method utilizes a detector that can detect high temperatures at the target to respond to missile defenses [5]. Missile design with an infrared system was used in France during World War I [6].…”

As a maritime country with a large area, besides the need to defend itself with the military, it also needs to protect itself with aerospace technology that can be controlled automatically. This research aims to develop an air defense system that can control guided missiles automatically with high accuracy. The right method can provide a high level of accuracy in controlling missiles to the targeted object. With the backpropagation neural network method for optimal control output feedback, it can process information data from the radar to control missile’s movement with a high degree of accuracy. The controller uses optimal control output feedback, which is equipped with a lock system and utilizes an accelerometer that can detect the slope of the missile and a gyroscope that can detect the slope between the target direction of the missile to follow the target, control the position, and direction of the missile. The target speed of movement can be easily identified and followed by the missile through the lock system. Sampling data comes from signals generated by radars located in defense areas and from missiles. Each part’s data processing speed is calculated using a fast algorithm that is reliable and has a level of accuracy and fast processing. Data processing impacts on the accuracy of missile movements on any change in the position and motion of targets and target speed. Improved maneuvering accuracy in the first training system can detect 1000 files with a load of 273, while in the last training, the system can detect 1000 files without a load period. So the missile can be guided to hit the target without obstacles when maneuvering.
