The proposed method searches the inverse maximum magnitude of the angle-sweep fractional Fourier domain and finds the optimum angle, which provides an estimate for the chirp-rate. In order to accelerate the search process, we propose to use the Fibonacci search algorithm, which provides a sub-optimal search scheme in terms of computational complexity. Simulation results show the efficiency of the proposed algorithm.  </span> <br> </p>}, number={1}, publisher={MUSA YILMAZ}
