Embodiment Construction
[0053] The present invention will be further described below in conjunction with the accompanying drawings. The embodiments of the present invention are used to explain the present invention, rather than to limit the present invention. Within the spirit of the present invention and the scope of protection of the claims, any modifications and changes made to the present invention fall within the protection scope of the present invention.
[0054] Refer to the attached figure 1 , the specific embodiment of the present invention is divided into the following steps:
[0055] Step 1 Construct L JN×1-dimensional main data vectors X from the echo complex amplitudes of L distance units to be detected l =[x l T (1),...,x l T (n),...,x l T (N)] T ,l=1,2,...,L; By performing radar irradiation on the target-free range around the area to be detected, the pure clutter auxiliary data adjacent to the distance unit to be detected that does not contain the target is obtained to form K J...
