umerical Deconvolution Method for Continuous Signals Processing and Its Application

A numerical deconvolution method is presented to recover signals of diagnoses in pulsed radiation fields simply and effectively. The vector of deconvolution recovery is obtained at a lower sampling frequency from an ‘over determined’ convolution linear equations set which is constructed by sampling output vectors and response vectors at a certain condition and is solved by least squares method at some physical constraints. The method is realized and simulated in Matlab. The simulated results show that the deconvolution solutions agree well with the input vectors without any additional process when the errors associated with the output vectors and the response vectors are less than 5%. The method is suitable for continuous signals processing and very accuracy results can be obtained in ill-posed problems solving. The reconstruction of the output vectors and the response vectors and the correction of the results are not needed by this method, which can be realized and operated conveniently. As an example, a successful application of the method in pulsed radiation field diagnosis was reported.
