In this paper, using the thought of acoustical match field to establish BTMA model, and the BTMA converted into spectral estimation problem is further introduced MUSIC spectrum signal processing and fast Fourier transform processing target motion parameter estimation. Numerical simulation results show that the subspace MUSIC algorithm is not stable. When the search step size is larger, the result will fluctuate greatly near the true value, and it can not converge to the true value accurately and stably, the fast Fourier transform method can get more accurate results.
Key words: Bearings-TMA; subspace MUSIC algorithm; fast Fourier transform
