ZHAO Xing-hao, TAO Ran. A New Method for Passive Radar MTD Based on the Fractional Correlation[J]. Acta Electronica Sinica, 2005, 33(9): 1567-1570.DOI:
A new method for passive radar MTD based on fractional correlation is presented by introducing the fractional correlation into the computation of the cross-ambiguity function (CAF).Compared with the FFT-based computation to CAF
the presented method can scan the target only in certain circular sector instead of the whole ambiguity plane
which may decrease the computational load.In addition
since sampling interval of both the angle and the radial can be chosen arbitrarily in the computation of the CAF
it removes the restriction of original time interval
and may provide the accurate estimation in both time-delay and Doppler shift.Finally
the method is also verified by the simulation examples.
