红外扫描系统一般采用旋转棱镜、扫描圆盘或旋转倾斜透镜,使目标扫过探测器面,从而产生导弹的跟踪或制导信号。在这些器件中噪声信号干扰了目标信号,因此影响目标的跟踪和控制。另外,一般的系统是用一个宽视场,故降低了导弹跟踪和控制所需的灵敏度。本文提出一种红外跟踪误差信号发生器。它是一个望远镜,其中有一个透镜和扫描机构。这种望远镜的瞬时视场小,所以对 Infrared scanning systems generally use a rotating prism, a scanning disk, or a rotating tilting lens that sweeps the target across the detector surface to produce a missile tracking or guidance signal. The noise signal in these devices interferes with the target signal, thus affecting the tracking and control of the target. In addition, the typical system uses a wide field of view, which reduces the sensitivity required for missile tracking and control. This paper presents an infrared tracking error signal generator. It is a telescope, which has a lens and scanning mechanism. The instantaneous field of view of this telescope is small, so right
