L型探测器瞬时视场建模及简析

Modeling and Study of IFOV of L-detector

通过数学建模的方法对L型探测器作了理论计算和讨论分析,得到了L型探测器的瞬时视场及在视场内存在四种不同的区域:线性区、非线性区、双解区和盲区。利用Matlab软件对某一条件下的瞬时视场及内部区域进行了数学仿真和计算,并分析了这四种区域形成的原因和对跟踪能力的影响,提出了一些消除或减小某些不利区域的方法。最后利用L型探测器的分析方法,得出了四元正交探测器的瞬时视场。

According to the modeling of L-detector, the four regions of the IFOV, including linear region, non-linear re- gion, double-solution region and blind region, were educed and simulated with Matlab. The reason of the appearance of the four regions and the effect on tracking ability were discussed. The methods of eliminating and minimizing the nega- tive areas were tabled. With the similar method, the IFOV of the cross-detector was obtained.
