Abstract :
It is difficult to detect the target submerged in the spread spectrum of the first-order sea clutter caused by the platform motion in shipborne high frequency surface wave radar (HFSWR). Based on oblique projection operators with steering vector, a technique for the target detection in the spread clutter spectrum is proposed in this paper, which can completely suppress interference coming from a known incident direction. The simulation and experimental results demonstrate reliable target detection and estimation in shipborne HFSWR.
