The research of base-band signal tracking processing of K Band ranging system

It introduced a processing method of base-band signal tracking of K Band ranging system(KBR)..and meanwhile gave the design method of base band signal tracking loop of KBR and the simulation results of Matlab. The DPLL can be easily implemented in hardware which is made up of DSP and FPGA. It also gave the basic hardware connection relationship of the special DPLL. This kind of method can track the dynamic situation of gravity satellite well, extract the quantity of carrier phase exactly and ensure that the static phase tracking error is less than 10^-4 Hz.
