摘要
针对舰载光电设备易受到载体摇摆、武器震动、烟雾,或是受到大气、云雾、海面杂波等环境影响而导致跟踪失败的情况,研制了能为伺服系统提供高精度的二次引导及控制视轴跟踪低空掠海目标的全息显控系统。将CA模型、有限记忆的最小二乘滤波和创新提出的"近似-比较"超低空控制技术相结合,提出了一种稳定跟踪低空掠海目标特别是为伺服系统提供跟丢目标角度信息的全息控制策略。介绍了该系统硬件设计与实现。试验证明,该全息显控系统在为光电设备提供外部控制信息和对外引导设备提供反馈信息的同时,能够连续6s提供比雷达引导精度高11.8′的二次引导数据及控制视轴稳定跟踪低空掠海目标的能力,实现了舰载光电设备全自动的无人职守。
The environment influences to shipborne optical-electronic equipment such as carri- er swaging,weapon shaking, fog or atmosphere, cloud and mist, wave of sea, it can result in tracking failure. According to this phenomena, a full information system that can offer high precision second lead to servo and control LOS to track ultralow-altitude target is manufac- tured. CA model,limited memory least-squares filter and the technology of ＂ Approximate- comparative＂ ultralow-altitude are combined, then tracking ultralow-altitude target and offer ing angle information of losing target to servo especially called full information strategy is in- troduced. The designing and accomplishing of hardware platform are discussed in the text. The experiments prove that the full information system not onry offer the information pro- vided by outer system and feedback the data provided by shipborne Optical-electronic equip- ment to outer system,but also offer second lead data to servo system,the precision of data is advanced 11.8＇ to radar for 6 s. The model has the ability to control LOS to track ultra low altitude target. It carries out a no man guard and automatic shipborne optical-electronic equipment.
