Abstract:
This paper proposes a time diversity based iterative frequency estimation scheme with low signal to noise ratio (SNR) for pulse Doppler radar based on weighted average. The conventional estimator can alleviate the effect of a diffused Doppler frequency. By applying a weighted average scheme to the received signal, the proposed algorithm improves the accuracy of the frequency estimation. The proposed estimator has better performance than the conventional estimators. Not only is the Cramer-Rao lower bound (CRLB) derived but also the performance of the proposed algorithm is analyzed and verified through Monte-Carlo simulations in an additive white Gaussian noise (AWGN).
