Proposed is a maximum likelihood (ML) estimation method to estimate the parameter of the moving target for high range resolution stepped-frequency radar in strong clutter background. In this study the temporal correlated clutter is used. By transmitting frequency-hopping waveform and using the spectrum density of the clutter, the method may accurately estimate the moving target parameter in strong...
Proposed is a maximum likelihood (ML) estimation and minimum target error function (TEF) method to estimate the parameters of the moving target for high range resolution stepped-frequency radar in temporal-spatial correlated clutter background. The compound-Gaussian model is used for the temporal-spatial correlated clutter. Both of the velocity and range of the moving target can be accurately estimated...
This paper concerns the fields of the eccentric payload crane systems. We firstly introduce a four-rope-driven self-levelling crane system, which can adjust the payload to level precisely and safely by changing the lengths of the ropes. Then, the system model is deduced according to force equation, moment equation principles and geometry restrictions, without considering the acceleration items. Finally,...
A generalized discrete time domain modeling and andlysis technique is presented for all types of switching regulaors using any type of duty-cycle controller, and operat1nq 1n both continuous and discontinuous inductor current. State space techniques are employed to derive an equivalent nonlinear discrete time model that describes the converter exactly. The system is linearized about its equilibrium...
