The invention relates to a method for carrying out breast tumor imaging by utilizing a microwave reflection time domain S21 signal. The method comprises the following steps: preparing a cavity breast model and a suspended tumor prosthesis; manufacturing a breast model with a tumor; connecting a transmitting antenna and a feeder line with a port 1 of a vector network analyzer; connecting a receiving antenna and a feeder line with a port 2 of the vector network analyzer; stimulating a measurement mode of a network analyzer time domain S21 signal; clinging the transmitting antenna and the receiving antenna and placing oppositely in a first-time measurement process; recording a transmission path time domain S21 signal at the moment; separating the transmitting antenna and the receiving antenna for a certain distance in a second-time measurement process; recording a new transmission path time domain S21 signal; subtracting the time domain S21 signal in the presence of the tumor prosthesis by the time domain S21 si
