Abstract EN
Millimeter-wave synthesis aperture imaging radiometer (SAIR) can realize high-resolution observations without requiring the real large aperture antenna.
Among the SAIRs, the Rotating Scanning SAIR (RS-SAIR) with linear sparse array is a popular system with low redundancy and high reliability.
However, due to the lack of matched imaging methods, its imaging precision is usually low.
For improving its imaging precision, a novel Cosine Matching Imaging (CMI) method is proposed in this paper.
In CMI method, according to the characteristic of rotating projection imaging, the angle-orientation image is constituted by the 1D projection images measured by RS-SAIR in a series of angles firstly.
Then, according to the trajectory of the target in angle-orientation image, the pixel values of the brightness temperature image are extracted by cosine matching method from the angle-orientation image one by one.
The simulation results demonstrate that the proposed CMI imaging method has higher reconstruction accuracy for the RS-SAIR.
