已经设计和评价了一种新式扫描传感器,它可在卫星轨道上监视导弹。该仪器称为环场传感器”,具有帧速高,空间分辨率好和辐射测量灵敏度高的优点,而所用的光学装置相当小。在物空间中的扫描由一只连续章动的平面镜完成,这只平面镜对飞船具有极低的动量交换。环场扫描综合了用于宽带系统的圆锥扫描线列和行扫描线列的绝大多数优点,并去除了它们的缺点。并且,环场扫描还可以在大视场内进行探测前滤波, 抑制背景。例如,将一只法布里-珀罗标准具接入光学装置中,就会改善信噪(背景)比。更重要的是它还能把对具有特定结构的背景的抑制能力提高一倍以上,而不需要大量的探测器。本文介绍了这种环场传感器,提出利用法布里-珀罗标准具可能提高信噪比的结果。文中包括有目标和背景的光谱,说明对传感器性能的估计是有依据的。
A new scanning sensor has been designed and evaluated that monitors missiles on satellite orbit. The instrument is called a loop field sensor and has the advantages of high frame rate, good spatial resolution and high radiation measurement sensitivity, and the optical device used is quite small.The scanning in object space is completed by a continuous nibbling plane mirror, The plane mirror has an extremely low momentum exchange for the spacecraft.The ring field scan combines the vast majority of the advantages of conical and linear scan line columns for broadband systems with their drawbacks removed and the field scan For example, inserting a Fabry-Perot etalon into an optical device improves the signal-to-noise (background) ratio and, more importantly, The ability to suppress background with a specific structure more than doubled without the need for a large number of detectors.In this paper, we introduce the loop-field sensor and propose the result that using Fabry-Perot etalon to improve the signal-to-noise ratio. The article includes both target and background spectra, indicating that the estimation of sensor performance is well-founded.
