摘要:
为了进一步提高干涉仪的测向精度,增强对宽带信号的适应能力和扩展系统的工作频率范围 ,以实现数字化宽带测向系统,提出了概率解模糊模型和基于最大后验概率的快速算法。仿 真结果表明,该算法解模糊速度快,解模糊能力强,误解模糊概率低,可广泛运用于干涉仪 等需要解相位差模糊的领域。

Abstract:
In order to improve the direction-finding(DF) precision of interferometer, enhan ce the ability of measuring the wideband signal and expand the working frequency range, and realize a digital wideband DF system, this paper proposes the probab ility phase difference ambiguity resolution model and fast algorithm based on MA P( Maximum a Posteriori). The simulation result shows the proposed algorithm is featured by fast resolution speed, strong resolution capability and low error re solution probability. It can find wide application in the field where phase diff erence ambiguity resolution is required.
