Effect of Wave-beam Number on the Beam Space High Resolution Algorithm

波束域高分辨算法充分利用目标先验信息,在提高分辨率的同时,降低了运算量。介绍了波束域高分辨算法。通过对信噪比门限的分析,给出了在不同波束数目下,高分辨算法估计精度和分辨概率结果,通过计算机仿真验证了结果的正确性。

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.
