This paper describes the design and realization of the azimuth preprocess in the real-time imaging processor of SAR with programmable logic device by the method of sub-aperture using band-pass filter.
According to the results discussed above, an ideal dielectric filter can be acquired by changing the coupling aperture diameter.
讨论结果表明，可通过调整滤波器耦合槽直径的大小，得到理想性能的介质滤波器。
