基于阵列扩展解模糊方法研究

Research of Ambiguity Resolution Technology Based on Array Extension

指出了长短基线法、参差基线法、无模糊长基线三种解模糊方法的各自缺点,介绍了四阶累积量MU-SIC算法原理和阵列扩展原理,并根据阵列扩展原理提出了在较小空间内放置三阵元均匀线阵扩展的解模糊方法,并进行了Matlab仿真,验证了方法的可行性。为解模糊方法提出了一个崭新的思路。

The defects of ambiguity resolution methods such as long-short baseline, stagger baseline, unambiguous long-baseline methods were presented. The principles of MUSIC method based on high-order cumulant and array extension were introduced. According to the array extension principle, a new ambiguity resolution method using uniform linear array（ULA） with 3 elements in smaller space was proposed. The simulation was performed under Matlab, and the simulation result indicates that this new method is feasible. A novel thought about ambiguity resolution problem was proposed.
