To measure projectile attitude in space flight,based on continuous wave( CW) radar,a new micro-Doppler effect testing technique is developed in this paper. It a
In order to precisely retrieve the atmospheric CO2,a retrieval method based on both near infrared(NIR)and thermal infrared(TIR)is established firstly.Then a loo
A noise estimator was presented in this paper by modeling the log-power sequence with hidden Markov model(HMM).The smoothing factor of this estimator was motiva
