In the passive locating and tracking system of single observer
an obtainment of Doppler Frequency Rate-of-Change is very important for the state estimation and location of a moving target.The Doppler Frequency Rate-of-Change is very difficult to estimate accurately because of its subtleness.Wavelet transform has the time-frequency localization characteristic and low SNR threshold.An algorithm based on wavelet transform is proposed to estimate the Doppler Frequency Rate-of-Change
the computer simulation study shows that this algorithm has low SNR threshold and obtain the parameter estimation fast and accurately.
