非对称干涉仪技术及工程实现

Asymmetric interferometer technology and engineering implementation

传统相位干涉仪一般要求各天线单元口径、增益均相同,面对高侦察灵敏度需求的应用场合,需采用基于阵列或抛物面等高增益的天线形式,传统多通道相位干涉仪工程实现代价较大。重点研究一个大口径和若干小口径天线组合的非对称干涉仪技术及其工程实现,突破低信噪比条件下相位差测量、实时测向处理等关键技术,推动非对称干涉仪技术的工程应用。

The traditional phase interferometer generally requires that the diameter and gain of each antenna are the same. Facing the application of high reconnaissance sensitivity demand, the antenna form with high gain based on array or paraboloid is needed. The traditional multi-channel phase interferometer is expensive to realize in engineering. Focus on the asymmetric interferometer technology and its engineering implementation of a combination of larger diameter and several diameter antennas, breaks through the key technologies such as phase difference measurement and real-time direction finding processing under the condition of low SNR, and promotes the engineering application of asymmetric interferometer technology.
