Abstract

The invention discloses a microwave staring imaging correlation method which comprises the following stepsof irradiating a target area object through a random radiation field and forming the distribution of the radiation field on an object surface; receiving a scattering field through a multi-channel or a single channel and carrying out electromagnetic field analysis to the imaging physical process of the target area object to obtain a time and space two-dimensional radiation field function corresponding to the object surface within the whole imaging area scope; counting the relevant characteristics of a time and space two-dimensional radiation field according to the time and space two-dimensional radiation field function; and carrying out correlated processing on the scattering field and the random radiation field according to the statistic characteristics to obtain the imaging of the target area object through inversion. The microwave staring imaging correlation method can be combined with the scattering field and the time and space two-dimensional radiation field to realize the high-resolution target imaging.

Description

technical field [0001] The invention belongs to the fields of radar technology, spaceflight remote sensing and precise guidance. Specifically, the invention relates to a correlation processing technology in microwave staring imaging. Background technique [0002] Traditional microwave staring radar imaging mainly uses real aperture technology. Real-aperture imaging radar is typically represented by beam-scanning radar. Its imaging processing technology relies on the correlation matching between the scattered received signal and the signal of the transmitting source. Since the signal of the transmitting source is not used in the spatial resolution of the target during this process, the The spatial resolution of the target only depends on the spatial configuration of the emitter array, that is, it is only determined by the beam width of the emitter array in the traditional sense, and the details of the illuminated target within the beam cannot be resolved. [0003] As one of ...
