[0024] The present invention will be further explained below in conjunction with the drawings:
[0025] Reference figure 1 , The implementation steps of the present invention are as follows:
[0026] Step 1. Obtain the echo data matrix X.
[0027] The radar transmitter emits a continuous pulse signal, and the pulse signal irradiates the surface of the object to produce an echo. The radar receiver receives the echo data matrix X. The echo data matrix X is a matrix of Q×M dimensions, where Q represents the echo The number of accumulated pulses of data, and M represents the number of distance units of echo data.
[0028] Step 2: Block processing of the echo data matrix.
[0029] The echo data matrix X is equally divided into B N×M-dimensional echo data blocks along the pulse dimension, where N represents the number of pulses of each echo data block, and B echo data blocks are respectively denoted as X 1 ,X 2 …,X b ,...,X B , X b Represents the b-th echo data block, b=1, 2,...,B, and the ...
