| Abstract: |
| In order to solve increasing of probability of false alarm caused by the marine
continuous wave(CW) radar sea clutter, as well as difficulty of sea clutter sup
pression algorithm engineering applications,a practical engineering sea clutter
suppression method is proposed. First, secondary detection is performed by bipar
ametric delete constant false alarm rate(CFAR) detection algorithm and statistic
al detection algorithm.Then,according to the feature that the target echo correl
atio
n between adjacent frames is strong and flaky sea clutter correlation is weak,th
e inter-frame processing is carried out. Simulation and sea experiments show th
at through appl
ication of the method marine CW radar can reduce the probability of false alarm
under different intensities of sea clutter. |
