Abstract :
This A new frequency estimator for Phase-coded pulse compression radar carrier frequency is proposed. First, via square nonlinear transformation, the radar signal is become one tone signal, it is possible that transformed signal is sub-nyquist sampled, and estimation value of carrier frequency will be ambiguous, a method of solving frequency ambiguity is proposed, and using FFT(Fast Fourier Transform) +FT(Fourier Transform) to improve carrier estimation precision, a method of fast peaks search is proposed. Simulation results show that the results are efficient.
