Abstract

In high frequency surface wave radar (HFSWR), Doppler frequencies of the vessels targets may overlap the first order Doppler frequencies from the sea clutter interference. Therefor it is hard to discover the vessel targets and estimate direction of arrive (DOA) of the ship targets. In this paper, the target direction finding method based on fractional Fourier transform (FRFT) was introduced for uniform acceleration/deceleration target, which used the frequency peculiarity difference between the targets and the first order sea clutter. Before the target DOA estimation, sea clutter were suppressed by FRFT method. The effectiveness of the method was verified by the simulations. The result demonstrated our method can estimate the DOA of targets in first order Doppler spectrum of sea clutter.
