Modeling And Simulation Of The Land And Sea Clutter And Study On The Techniques Of Target Detection

Land and sea clutter modeling for near costal region and target signals detection approaches were researched in this paper. First, several typical classic clutter models were analyzed and their statistical properties and simulations for ZMNL were also discussed. Second, with regard to the issue of small physical realizability for former filters, the minimum-phase and cepstral simulation technologies were used to improve the physical realizability of the system. Features of general compound clutter model (GC-PDF) were studied and the least squared method and the parameter estimating method through the parameter decoupling method were introduced and compared by simulation tests. A compounded clutter model was described based on the near costal region and several typical clutter model theories. Simulations were taken towards their statistic features. LFM(Linear Frequency Modulation) based on WVD(Wigner Ville Distribution) transformation was adopted in the detection of targeted signal and proved to be effective by the simulation tests.
