The general optical countermeasure simulation model is established by using photoelectrical countermeasure simulation test to conduct the estimation of countermeasure effect. The target-missing quantity of guided weapon and guided precision is designated as evaluating index. Whether the disturbing is valid or not is based on Whether the target-missing quantity is more than 3 times of normal guided precision without disturbance or not. 2011 IEEE.   Electro-optical imaging system identification using pseudo-random binary pattern (EI CONFERENCE) 会议论文 2010 International Conference on Computer, Mechatronics, Control and Electronic Engineering, CMCE 2010, August 24, 2010 - August 26, 2010, Changchun, China Le Y.; Jian W.; Jianzhong Z.; Qiang S.; Jianzhuo L. 收藏  |  浏览/下载：16/0  |  提交时间：2013/03/25 A method using pseudo-random binary pattern is developed for electro-optical imaging system identification. The imaging system is taken as a stable  linear  time-invariant  and causal filter  and its transfer function is measured through the pseudo-random binary sequence impulse responses identification. A digital mirror device (DMD) light projector is developed as the target generator  and wavelet thresholding is used to denoise the captured image. Pre-filtering spectral estimation algorithm with adaptive parameter selection is also proposed for the identification process  overcoming the challenge brought by the size limit derived from the optical isoplantic region. Simulations and experiments are presented to show the effectiveness of the proposed method.0-64. 2010 IEEE.
