无目标

The feasibility of the two proposed methods is verified by computer simulation.4、A single receiving station passive radar system framework based on Software Defined Radio is proposed. Receiving directly signal, scatted signal use an array antenna simultaneously in the radar system. Therefore, the hardware structure of the system is simplified, Maneuvering and Flexible design are improved.

And the traditional passive filter's function is also limited for avoiding the resonance and harmonic enlarging. The auto-compensator and harmonics shielding converter transformer can be used to solve these problems, which is based on the principle of the winding ampere and turn's balance. This paper elaborates this kind of transformer filter mechanism. In the view of the HVDC system, a new winding connection plan is proposed, and the filter optimization model is created.
