FFT Algorithm for Calculating the SALS Patterns from Anisotropic Objects Immersed in an Isotropic Matrix;

Implementation of DSP on FFT in Virtual Instrument;

And the frequency response of this inverter is obtained using FFT via the Matlab Simulink.

Vortex signal processing based on wavelet transformation and FFT algorithm

In order to test science character and a pplicability of the algorithm, we compare with a kind of improving FFT algorithm which implements in the Super Computer, and analyze their results.

Based on the analysis of serial FFT algorithm and its shortage, this paper presents studies from theoretically analysis that FFT algorithm of dishing network has higher accelerate ratio and total efficiency when it is parallel processed, it is significative to realize the parallel real-time system of FFT algorithm.

At present, FFT arithmetic is widely applied in the disposal of the data signals, which is disposed by software.

This paper analyzes the principle of 2-based FFT arithmetic , designs a VB-based program to realize it and tests the computing time of the pr ogram and the result indicates its applicability to the real-time signal proces sing, finaly verifies the part of trasform of the above program in MATLAB.

The principle of level measurement radar and the FFT/CZT arithmetic used to improve radar measurement precision in detail are introduced, and realization plan based on DSP is given.
