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.
In this paper, according to the strict realtime requirement of the signal processing of a fuze, the application of the single chip digital signal processor (DSP) in the fuze design is explored.
This design USES digital signal processor (TMS320LF2407 DSP) as a control chip, which helps the system to improve the real-time control capability and data processing capability.
