A New DOA Estimation Algorithm Based on Fractional Fourier Transform for Wideband LFM Sources
A new method based on the fractional Fourier domain signal subspace decomposition for DOA estimation of wideband LFM sources in sensor arrays is introduced.The proposed approach detects LFM sources with fractionaI Fourier transform(FRFT),estimates their parameters,and constructs the fractional Fourier domain correlation matrix of the sensor array signals as well as the steering vector cOrresponding to each source.The MUSIC algorithm is then used to estimate the DOA of LFM sources.Its performance is numerically evaluated.
