Blind time‐domain motion compensation for synthetic Doppler spectra obtained from an HF‐radar on a floating platform

Abstract A method for time‐domain motion compensation of high frequency (HF) radar signals the case a floating transmitter and fixed receiver is proposed when parameters (including amplitude angular motion) are not known priori. In this study, platform assumed to follow single‐frequency model. Additionally, instead trying estimate from received motion‐contaminated Doppler spectrum, which proportional observed cross‐section ocean surface platform, autocorrelation function electric field estimated, related by application an inverse temporal Fourier transform. By comparing locations zeros antenna with that on finding associated motion, estimated. These matched actual parameter values, motion‐compensated spectrum recovered platform.
