Wideband Scaled Radon-Fourier Transform
With respect to the scale effect of wideband radar echoes, this paper proposes a long-time coherent integration method, i.e., wideband scaled Radon-Fourier transform (WSRFT). It can make great improvement on the detection performance of far-range, weak and high speed target of wideband radar. The degradation of pulse compression performance caused by scale effect is studied. Range and velocity shifts of the output of standard RFT (SRFT) are analyzed. Furthermore, the detection performance comparison between WSRFT and SRFT is investigated. Finally, detailed numerical experiments are provided to demonstrate the effectiveness of the proposed WSRFT.
