This work is concerned with developing the frequency-based jamming technology against SAR. Firstly, the shift frequency jamming to LFM radar and SAR is analyzed. Then a modified shift frequency jamming to SAR, stepped shift frequency jamming (SSFJ), is presented and discussed. The theoretic research and simulation show that the SSFJ is inter/intra partly coherent with the SAR system and has a region...
This paper presents the design of one real-time imaging system in airborne C-band Synthetic Aperture Radar. The real-time imaging algorithm based on subaperture-division is described in detail. In order to meet real-time signal processing the signal processing board with 8 ADSP-TS201S digital signal processors and 2GB SDRAM is designed. This system has excellent real-time processing ability and tremendous...
