In order to solve the microwave imaging problem which has great demand in the fields of radar, guidance, security and medical treatment, the microwave array fast imaging technology based on lens imaging principle is analyzed. Based on the analyzing of imaging characteristics and algorithm, a fast algorithm suitable for array imaging is proposed. In this method, only one-time IFFT(Inverse Fast Fourier Transform) operation is needed to obtain the image of the target. The proposed new method greatly reduces the complexity of the algorithm and has a faster computing speed. Finally, imaging verification is carried out. The microwave anechoic chamber is used to measure the near field data of the scattering source, and the image of the target is calculated. The experimental results confirm the effectiveness of the new fast imaging algorithm. |
