The invention relates to a rectangular waveguide-based sweep frequency microwave imaging system based on matrix decomposition. The rectangular waveguide-based sweep frequency microwave imaging systemcomprises a computer, a display unit, an XYZ displacement mechanism, a directional signal beam splitting circuit, a signal analysis unit, a microwave signal source and a waveguide, wherein the computer is connected with the XYZ displacement mechanism by a serial port, controls the XYZ displacement mechanism to move the waveguide and executes data acquiring and processing; the display unit displaysa final detection result image; the XYZ displacement mechanism moves the rectangular waveguide or a detected object, realizes control over the detection distance between the waveguide and the detected object and acquires detection data; the directional signal beam splitting circuit separates and directs part of a transmission signal and a reflection signal; the waveguide is a rectangular openingwaveguide and realizes tran
