چکیده
State-of-the-art automotive radar sensors use a Mutliple-Input Mutiple-Output (MIMO) approach to obtain better angular resolution. Time-Division Multiplexing (TDM) scheme is commonly applied realize the orthogonality in time at transmitter. Apart from its simplicity implementation, TDM has drawback of reduced maximum unambiguous Doppler proportional number transmitters. In this paper, phase difference based disambiguation method proposed regain which equivalent only one This works well when transmitters large. The demonstrated with simulation and measurement data.

A Three-Dimensional Variational Data Analysis Method with Recursive Filter for Doppler Radars
In this paper, a new method of dual-Doppler radar wind analysis based on a three-dimensional variational data assimilation (3DVAR) approach is proposed. In it, a cost function, including background term and radial observation term, is minimized through a limited memory, quasi-Newton conjugate-gradient algorithm with the mass continuity equation imposed as a weak constraint. In the method, the b...
متن کاملDoppler Weather Radars and Wind Turbines
In many countries the number of wind turbines is growing rapidly as a response to the increasing demand for renewable energy. The cumulative capacity of wind turbines worldwide has shown a near 10-fold increase in the last decade (Global Wind Energy Council, 2011) and in the coming years many more wind turbines are expected to be built. Existing, older wind turbines are likely to be replaced by...
متن کاملA Variational Method for the Analysis of Three-Dimensional Wind Fields from Two Doppler Radars
This paper proposes a new method of dual-Doppler radar analysis based on a variational approach. In it, a cost function, defined as the distance between the analysis and the observations at the data points, is minimized through a limited memory, quasi-Newton conjugate gradient algorithm with the mass continuity equation imposed as a weak constraint. The analysis is performed in Cartesian space....
