综合考虑传统测向体制特点,在干涉仪测向原理的基础上,为了消除相位模糊和兼顾测向精度,设计了比幅测向解最短基线模糊方法,并对其测角精度要求进行了分析,仿真结果表明该方法可行。从安装要素出发,为提升其适装性,提出联合测向天线系统采用共形设计方法,进而改善系统对空中辐射源目标的测向性能,大幅提高系统综合作战效能,在实际工程应用上具有一定的实用和参考价值。

Considering the characteristics of traditional measurement direction systems,for eliminating the phase ambiguity and covering the precision of direction finding, a method for dispelling the ambiguity of short-baseline using amplitude comparison direction finding is designed, and the precision of direction finding is analyzed on the basis of interferometer direction finding theory, the simulation results show that the method is feasible. For improving the mounting adaptability, a design method of conformal antenna system based on joint direction finding is proposed, and then the performance of measurement direction for the air radiation source target is improved, the comprehensive combat effectiveness of the system will be greatly improved, showing great practical and reference value for actural engineering appliction.
