A DC high voltage amplifier developed using amplitude modulation includes an amplitude modulator, a power amplifier, a step-up transformer, and a linear detector.

Aimed at the difficulties to get the closed solution of probability density of detector background power intensity estimation in the analysis of CFAR detector after radar linear detector output, two methods of theoretical analyses of CA-CFAR detection performance were synthesized by using the approximate Rayleigh distribution of mixing multi- 2 probability density and central limit-based theorem.

Starting with properties of cubic parabola, it is demonstrated elementarily that solving elliptic equations using Jacobian elliptic functions, analytic solutions for a class of nonlinear wave equations and properties of nonlinear waves can be obtained, especially for solitary waves.

In this study, numerical analyses for solving the generalized Biot s dynamic consolidation equations by virtue of finite element method are performed on dynamic response of sandy seabed subjected to non-linear wave loading in the shallow water region.

Based on the generalized formulation of two-dimensional Biot s theory, a finite element numerical method in time domain is developed to evaluate the dynamic response of saturated elastic seabed subject to linear or non-linear wave loadings.

At present, the calculations of wave forces on marine structures are confined to the linear and low-order non-linear wave theories, sometimes these are not satisfied with the requirements.
