Abstract :
At present, the spatial spectrum estimation techniques are often used for one-dimensional parameter estimation of target, while estimate multi-dimensional parameter of target is a more broad application prospects. The paper use G-S orthogonal algorithm to estimate space time two dimension parameter of target, and research the combination estimation problem of azimuth and carrier frequency. Stimulation shows linear array GS orthogonal algorithm can be extended to the uniform circular array, space and time domain can be a joint deal with the estimated parameters of the realization of multi-dimensional parameter estimation.
