摘要
从干涉仪线阵测向系统和均匀线阵DBF测向系统的组成和工作原理入手,介绍了两种测向系统的处理流程,推导了方位估计的C-R下界,通过对C-R下界的分析,对比了两种测向系统的性能,并根据两系统的工作特点,分析其应用场景。所得结论对工程人员具有重要的参考价值。
The system composition, operating principle and process flow of linear array interferometer and uniform linear array DBF are introduced firstly. Then, the Cramer-rao lower bounds） CRLB） for each method of direction-finding are deduced. A comparison of direction-finding performance is done through CRLB. An analysis of application scenarios is done according to their features. Some conclusions are significant and valuable to engineers in system design.
