基于运动特征的干扰弹检测方法研究

在红外成像导引头视场中，及时检测出干扰弹是红外成像导引头实现抗干扰弹干扰的前提。在弹目距离较大时，导引头处于点目标跟踪阶段，目标信噪比比较低，且没有目标形状特征可以利用，因此，对干扰弹的检测比较困难。利用干扰弹与目标运动特征的不同进行干扰弹检测是一种比较有效的方法，通过对比仿真选择目标图像在焦平面上的运动加速度作为特征量进行干扰弹检测。最后，通过数字仿真，研究了在考虑误差的情况下，各种因素对干扰弹检测概率的影响。

Study on Detection Method of Decoy Based on Motion Characteristics

Detection of the decoys in the field of view (FOV) of the imaging-infrared seeker (IIR) is important for IIR to track the true target aircraft. It is not an easy thing when the target image only has several pixels. One of the most effective discrimination in IIR is motion characteristic of the target. The acceleration of the target image on the focal plane arry (FPA) is selected as motion characteristic quantity to find decoys in IIR FOV and is verified by digital simulations. The decoy detection probability is studied.
