This paper proposes a new high reliable unilateral inductive axle counting sensor prototype based on eddy-current principle. It could send out strong analog signal several kilometers away without any trackside or inner magnifying circuits because of its special open flux magnetic structure and signal processing method. The operational principle of the sensor is studied with modeling as well as the...
This paper studies the processing methods of non-cooperative of GPS signals. The non-cooperative receiver structure are firstly developed, then their math models are analyzed, and finally computer simulations are used to evaluate the performances. Theoretical analyses and simulation results reveal that the methods have an application widely.
