Method and system for extracting target signal based on maximum correlated kurtosis deconvolution

A system for extracting a target signal based on maximum correlated kurtosis deconvolution (MCKD), comprising:

• a plurality of antenna pairs, a vector network analyzer, and a computer;
• wherein
• the plurality of antenna pairs are connected with the vector network analyzer, and the vector network analyzer is connected with the computer;
• the plurality of antenna pairs are arranged along circumference of a brain of a subject to be tested;
• wherein each of the plurality of antenna pairs comprises a transmitting antenna and a receiving antenna;
• the transmitting antenna is an antenna for transmitting a signal, the receiving antenna is an antenna for receiving a signal, and the antenna pairs are configured to acquire a microwave signal of the brain of the subject to be tested;
• the vector network analyzer is configured to receive the microwave signal of the brain of the subject to be tested, and transmit the microwave signal of the brain of the subject to be tested to the computer;
• and
• the computer is configured to:
• obtain the microwave signal of the brain of the subject to be tested;
• filter the microwave signal by using the MCKD;
• perform mode decomposition on the filtered microwave signal by using a complete ensemble empirical mode decomposition with adaptive noise (CEEMDAN);
• and
• perform image reconstruction on the decomposed microwave signal by using a delay sum beamforming to obtain a target bleeding image.
