Time-frequency method for detecting an accelerating target in sea clutter

  title={Time-frequency method for detecting an accelerating target in sea clutter},

  journal={IEEE Transactions on Aerospace and Electronic Systems},
The authors design a time-frequency (TF) method for use in high-frequency surface-wave radar (HFSWR) for detecting a small accelerating target in sea clutter. The clutter is modelled by pseudo targets moving with Bragg velocity towards and away from the radar. The design is based on the Wigner distribution (WD) defined by Chan (type-III WD, in our terminology) rather than the WD defined by Claasen and Mecklenbrauker (1980) (2times type-I WD, in our terminology). Like the type-I WD, the type-III… CONTINUE READING
