A Frequency Estimation Algorithm for Pulsed Magnetron Radar Transmitter Sample Signal

the pulsed magnetron Cloud sounding radar is one of non-coherent radar, a magnetron has a random starting phase and its frequency chirps during the transmit pulse. This paper presents a frequency estimation algorithm for pulsed magnetron radar transmitter sample signal, based on the modified Wigner-Ville time-frequency analysis. From the three groups' data of compared simulation experiment, at any condition, this paper method can get higher performance than FFT method, and can get measurement mean error less than 0.105% at low algorithm complexity. The method can be used as frequency discriminator in pulsed magnetron Cloud sounding radar AFC real-time hardware system.
