| Abstract: | This paper introduces mainly a scheme of PD radar range tracking. The operation principle and performance of PD radar range tracking system are analyzed and studied by using computer simulation technology of MATLAB/SIMULINK. Furthermore, the functions of all modules and the algorithm of deviation calculation circuit in this model are described. The scheme accomplishes range tracking by adopting three range gate tracking to make middle gate always centered at echo pulse center through feedback circuit and deviation calculation circuit. Simulation results show that the scheme has good tracking performances. |
