Abstract :
Distributed radar system is helpful to detect small targets in the space. However, Doppler frequency may not only cause the gain lose after signal compression, but also decrease the accumulation gain of the fusing center. Two methods including match filter banks and Fractional Fourier Transform (FRFT) are investigated to compensate the Doppler frequency of the distributed radar system, and their performances are evaluated.
