本文研究了用光学探测器阵列对目标方位角的判定。提出了这一判定的最大似然算法,同时述及较简单的次优算法。本文尚分析了最大似然判定的性能,指出了对小的探测器束宽,阵列精度即为目标方位角的振荡函数。最小阵列精度A决定于探测器東宽和阵列中探测器的数目N。N越大,A也越大;对于给定的N,可以找出相应于最大精度的最优束宽。最优束宽意味着探测器波束的100％重叠,即探测器灵敏度的半角应等于探测器间的角距。
This paper studies the determination of the azimuth of an object using an optical detector array. The maximum likelihood algorithm of this decision is proposed, and the simpler suboptimal algorithm is also mentioned. In this paper, the performance of maximum likelihood decision is analyzed, and for a small detector beamwidth, the array accuracy is the oscillation function of the target azimuth. The minimum array accuracy A depends on the detector east-wide and the number of detectors N in the array. The larger N is, the larger A is; for a given N, the optimal beam width corresponding to the maximum accuracy can be found. The optimal beamwidth means 100% overlap of the detector beam, ie the half angle of the detector sensitivity should be equal to the angular distance between the detectors.
