Reasearch on The Detection of Close-to-Sea Flight Missile with Infrared Imagining Based on The Method of Wavelet Transform

首先给出小波变换的算法原理;然后采用二维小波详细分析了低空掠海飞行反舰导弹目标的基本检测原理和检测方法;最后采用MatLab模拟得出了在强太阳光照射条件下低空掠海飞行反舰导弹目标的检测图像。仿真结果表明,利用小波变换方法能够较为有效地检测出强红外背景下的掠海飞行的导弹信息,并且具有较高的探测精度、能够满足探测预警实时性要求等优点。

This paper firstly presents the arithmetic principle of the wavelet transform; then analyses the basic detection principle and the detection method of the close-to-sea anti-ship missile making use of the two dimension wavelet; finally, on the background of the strong sunshine, obtains the detection image of the close-to-sea anti-ship missile by the method of MatLab simulation. The simulation outcome indicates that the missile can be detected effectively on the strong infrared background by the use of wavelet transform, this method have high detection precision and it can satisfies the request of the real-time detection and pre-warning also.
