A novel sea clutter suppression method based on SVD‐FRFT at low signal‐to‐clutter ratio
Electronics Letters, 2023 The target and sea clutter Doppler domains frequently overlap due to the frequent passage of slow ship targets through the sea clutter zone. In this letter, a novel sea clutter suppression method is suggested as a solution to this issue, whose key is a ...

The Application of JDL to Suppress Sea Clutter for Shipborne HFSWR [PDF]
International Journal of Antennas and Propagation, 2015 This paper deals with the problem of sea clutter suppression for shipborne high frequency surface wave radar (HFSWR) based on the joint domain localized (JDL) adaptive processing algorithm. The performance of the novel method is compared with 2D FFT plus
