Intelligent Laser Angle Detection Using Fuzzy Data Fusion

Laser warning receiver is the basic materiel for implementing laser countermeasure. It is very significant with regard to effectively self-protect and destroy the enemy in battlefield. Its function is to detect incidence laser signal, to measure laser parameters. However, Most of the existing system has a complex hardware especially if it gives the direction of the incident laser. In addition, it may face the problem of background sun light suppression. In this paper a simple intelligent algorithm for laser angle detection is proposed using fuzzy logic data fusion to detect laser incidence angle for early warning. The proposed system is simulated and tested using MATLAB software using four laser sensors to detect the incident laser angle from 0 to 360 and an additional sensor to distinguish the incidence laser from background sun light.
