Abstract

This paper provides a novel method for estimating the parameters of linear frequency modulated(LFM) signals, or the so called chirp signals, based on a modification to the filter bank approach of the maximum likelihood estimation. This method reduces the computational complexity of ML method. By using numerical simulations, the performance of the new approach are verified. Also we apply the algorithm to the raw data of an X-band airborne SAR with 3m×3m resolution. Moving targets are successfully focused.
