为了得到一个实际系统的设计,必须解决具有高角精度的干涉仪的模糊问题。本文叙述了一种解决模糊问题的新方法,它是建立在运用干涉仪天线单元的单脉冲电路基础上的。系统的总角精度由干涉仪得到,单脉冲分系统的角精度用来解决干涉仪的模糊。推导了正确解决模糊的概率公式,它是单元尺寸和单脉冲精度的函数,这说明:当干涉仪单元的尺寸为干涉仪基线的几分之一时,结果引起的模糊解决匹配概率高。最后在一般单脉冲和干涉仪的系统设计之间对以下三个主要参数做了比较:信号灵敏度、角精度和视场大小,这些决定了实际应用中的适当选择。对这些应用来说干涉仪比单脉冲系统更适合,它们的角精度和视场比信号灵敏度更为重要。
In order to get the design of an actual system, it is necessary to solve the problem of blurring the interferometer with high angular accuracy. This article describes a new method to solve the problem of ambiguity, which is based on a monopulse circuit using interferometer antenna elements. The total angular accuracy of the system is obtained by the interferometer, and the angular accuracy of the single-pulse subsystem is used to resolve the blur of the interferometer. The probability formula for correctly solving the ambiguity is derived as a function of cell size and monopulse accuracy, which shows that the result is a high probability of ambiguity resolution matching when the size of the interferometer cell is a fraction of the baseline of the interferometer. Finally, the following three main parameters are compared among the general system design of single pulse and interferometer: signal sensitivity, angular accuracy and field of view, which determine the appropriate choice in practical applications. Interferometers are more suitable for these applications than monopulse systems and their angular accuracy and field of view are more important than signal sensitivity.
