Example Embodiment
[0020] The technical solution of the present invention will be described clearly and completely below. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0021] The fast two-dimensional CFAR target detection system in this embodiment includes a coherent accumulation result reading module, a distance dimension CFAR detection module, and a speed dimension CFAR detection module.
[0022] Further, the coherent accumulation result reading module is used to read the two-dimensional coherent accumulation result, denoted as A(n,m), where m=1, 2,...,M, n=1, 2 ,...,N, M and N respectively represent the number of velocity units (ie the number of FFT points) and the number of distance dimension points.
