Abstract :
Proposes an efficient novel method for Doppler frequency estimation in MTI radar, based on white noise assumption and using a second order canceler in the receiver. These conditions make the MA (moving average) model valid. Based on some realistic numerical assumptions, the authors compare the results of this model by a classic FFT (fast Fourier transform) estimator. By presenting a performance analysis, the authors show the degree of improvement which can be obtained by the proposed new estimation method
