Abstract :
An algorithm of target tracking based on adaptive waveform design was proposed with the help of Doppler estimation theory. According to the analysis of the ambiguity function for liner frequency modulation signal, a model between ambiguity function of the signal and Cramer-Rao bound of time and frequency delay was built. This paper realized the target tracking by adjusting the frequency width and pulse width using Kalman filtering method. With the same signal energy and noise environment, the simulation results show that the proposed adaptive tracking algorithm has a better tracking precision than the method which makes use of the constant parameter.
