Abstract 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. The azimuth preprocess circuit implementation and its result are presented. It can be gotten that the circuit performance is satisfactory in operation efficiency, integration degree, implementation convenience and expandability.

Key words： Synthetic aperture radar Sub-aperture imaging process Azimuth preprocess Data-collection rate reducing Programmable logic device
