Linear FM Signal Estimation Method Based on Linear Iterative Prediction

  • Received Date: 18 Dec 2008
  • Publish Date: 12 Nov 2009
  • To enlarge the parameter estimation range in the algorithm for estimation of LFM (linear frequency modulation) signal parameters,and improved algorithm was proposed based on the method of rotate-add-decimate (RAD) for frequency measurement,and it was implemented with the method of linear iterative prediction.It increases the estimation range to (-π/2,π/2) on the premise of ensuring linear FM (frequency modulation) ratio and estimation precision.Simulation demonstrated the effectiveness of the algorithm.
