[0002] The dual-frequency synthetic aperture utilizes the characteristics of signals of different frequencies and improves the resolution of the image through comprehensive processing. Compared with the traditional single-frequency synthetic aperture technology, the dual-frequency synthetic aperture utilizes phase correction and weighted summation of signals of different frequencies to greatly improve the resolution of the image, which is very helpful for target recognition and positioning. And because the dual-frequency synthetic aperture utilizes signals of two different frequencies, it can better resist noise and interference, which makes it possible to obtain clear and reliable images in complex environments.
