- W2355241852 abstract "An algorithm of detecting target radiated noise lines and estimating frequencies of the lines is presented. The algorithm is composed of a coarse search and a fine search after removing a trend in a times series of radiated noise with Wagstaff' s method. The coarse search of the frequency is made by FFT and the fine search of the frequency is estimated by an interpolation scheme and a modified Newton-Raphson' s method. Experimental results on sea trial data and simulation data show that the detection performance of the proposed method is superior to that of FFT method by 3~8dB. Also it is demonstrated that the proposed method results in a frequency estimation performance nearer to the Cramer-Rao Bound than FFT method dose." @default.
