基于全相位的分频融合分层算法研究
Research on Points-Frequency Fusion and Hierarchy Algorithm Based on All-phase Method
摘要
Abstract
For the signal of fast change of frequency,the advantage of the points-frequency fusion algorithm is high precision and strong noise immunity,but the precision is effected by phase difference and poor real-time. So the points-frequency fusion and hierarchy algorithm based on all-phase. The hierarchy algorithm is put forward to reduce the large amount of real-time computation in the multi-loop,the computation is several times reduced without decrease precision. The all-phase spectrum analysis algorithm is put forward to decrease the error of phase difference. As shown in theoretical analysis and comparison experiments,the algorithm is increased effectively in the process of points- frequency fusion.关键词
