Embodiment Construction
[0028] 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.
[0029] Refer to the attachedfigure 1 , the specific embodiment of the present invention is divided into the following steps:
[0030] Step 1: Obtain the pure clutter auxiliary data adjacent to the distance unit to be detected by irradiating the target-free range around the area to be detected, and form R auxiliary data vectors x m ,m=1,2,...,R, L data vectors z to be detected are formed by the echo complex amplitudes of L distance units to be detected t , t=1,2,...,L, and send the data vector to be detected and the reference data vector to t...
