Abstract :
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.
