摘要

本文提出了一种基于子带分解DFT(SD-DFT)的快速局部细化频谱分析新方法——子带谱分析(SSA).它兼有现行诸多细化分析方法之优点

而又避免了它们的主要缺点.文中给出了SSA的应用实例.

Abstract

In this paper

a new fast partial spectrum computation method called subband spectrum analysis (SSA) is presented

which is based on the theory of subband decomposition.The new method not only holds the high-resolution feature of ZFFF using complex modulation

but also has the advantages of simplicity

easy implementation

less arithmetic operations and memory requirements.SSAalgorithm has been successfully used in the maneuvering target velocity tracking system.Accuracy and efficiency of the method are proved by the simulation results.
