Summary:The traditional DOA (Direction of Arrival) estimation algorithms can't estimate the direction of signals expect assuming the source of signals are smooth. They become invalid when dealing with the signals with the smooth circulation characteristics. Therefore the paper proposed a new algorithm based on circulation statistics for MIMO (Multiple Input and Multiple Output) radar and achieved the purpose of estimating the DOA of cyclostationarity signals. As one-dimensional array can only estimate the azimuth of signal, but in real circumstance, the target attitude also includes the angle of pitch. For that, this paper applies the MIMO radar of cross array, to realize the aim of estimating both angle of pitch and azimuth at the same time.
