不定方程求解在直角测向阵模糊收敛中的应用

Application of Diophantine Equation Solution in Ambiguity Convergence of Orthogonal Direction Finding Array

针对星载干涉仪测向体制中存在的模糊问题,利用天线阵元间环型相位约束关系,将解模糊问题转换为对多元一次不定方程的求解问题,并给出了解模糊的过程。仿真与验证表明,该方法较常规方法在计算上具有较大的优势。

For the problem of interferometer direction finding ambiguity, an algorithm of solving Ambiguity based on the Restriction relationship of the phase between sensors is given, which converts the process of solv- ing Ambiguity to the Solution of Diophantine Equation. By simulation and practical verification, it＇s proved that the new method has better performance in the calculation than conventional method.
