Beam space high resolution algorithm makes full use of the prior information of the objects, can not only improve the resolution, but also reduce the calculation amount. This paper introduces the beam space high resolution algorithm, and gives out the assessment accuracy of the high resolution algorithm and the result of resolution probability under different wave-beam numbers by the analysis of SNR threshold. And the correctness of results are verified through computer simulation.
