Time-Delay Estimation for Complex LFM Signal Based on Cyclic Cross-Correlation Amplitude

In this paper, the time-delay estimator of complex LFM is discussed and constructed based on the cyclic cross-correlation amplitude. Then, the mean and variance of estimating error are deduced and the estimator performance is analyzed in detail. Finally, the performance of the estimator is given through computer simulation, which is in agreement with the analytic results
