Abstract:
The current parameter estimation algorithms of chirp rate have high complexity and long calculation time, meantime they are difficult to achieve high estimation rate. Therefore, in order to overcome these problems, in this paper, a new parameter estimation algorithm based on Holder coefficient is presented. Firstly, this algorithm calculates the correlation curve of the Holder coefficient value under different chirp rate. Secondly, this algorithm calculates the correlation curve under different SNR. Finally, the fitting curve expression can be got by the correlation curve, and then the estimation value of chirp rate can also be got. The theory analysis and simulation results show that this algorithm is simple and easy to realize, and has much better application value for real-time estimation.
Key words: parameter estimation LFM signal chirp rate holder coefficient correlation curve
