摘要
分析研究了红外成像导引头对远距离目标的截获问题 ,总结了红外成像导引头点目标截获问题的特点与难点 ;给出了与基于形态学背景预测的点目标检测算法相配套的点目标截获算法。仿真试验结果表明 ,该截获算法能够迅速有效地截获虚警目标较多的导引头视场中的点目标 ,并能有效剔除虚警目标。文中的点目标截获方法具有很强的通用性。
In signal processing of Imaging Infrared (IIR) seeker of air to air missile (AAM), the point target detection is one of the key technologies. After analyzing the small target acquisition problem, a rapid acquisition method for IIR seeker was introduced and simulated. The method includes: tracking gating, data association, tracking maintenance, tracking initiation and termination, and α β filter. After the image processing algorithm extract candidate targets from the IR image of the sensor, the acquisition method separates target from false alarm targets quickly. Four different IR image sequences were used to analyze the algorithm performance by a large number of simulation experiments. The results show the method can be used for target acquisition in very low SNR conditions.
