Abstract

Abstract: Aiming at the key problem of high-precision tracking loop design of a measurement radar for the weak signal (low carrier to noise ratio signal) in dynamic environment, the design and optimization methods of carrier tracking loop and code tracking loop are focused on. A signal structure with a single carrier as a pilot is proposed, and the loop structure of the frequency-locked loop and the phase-locked loop working together is studied. The modeling and simulation on the two structures show that for the week signal tracking in a dynamic environment, the loop combination structure of the frequency-serial auxiliary phase-locked loop performs better. For the code tracking loop, a combination of wide and narrow correlation spacing is provided. The optimal loop bandwidth design of the code loop under the principle of minimum tracking error is obtained by modeling and calculation. Simulations verify the validity and reliability of the algorithm and parameter design.
