| 摘 要： | 对稳像火控系统中目标角速度的测量过程进行了分析,指出采用自动传感器测量目标角速度仍存在误差,且对射击诸元的影响较大;在计算机采集数据的有限时间段内,该误差序列为均值不为零的随机干扰噪声,采用均值—中值加权滤波方法可有效减小该嗓声对射击诸元影响.

| Abstract: | This paper analyses the target angular velocity measuring process in the image stabilizing fire control system, points out that errors still exist in measuring target angular velocity with automatic sensors and they can cause serious effect on the firing data. Within the limited time for the computer to collect data, the error series are additive disturbance noise of non-zero mean square value. The introduction of average-mean value filter can effectively reduce the influence on the firing data caused by such noise. |
