This paper considers the coherent integration problem for a maneuvering target with jerk motion, involving range migration (RM) and Doppler frequency migration (DFM) within the coherent integration period. A fast non-searching method based on adjacent cross correlation function (ACCF) is proposed to realize the coherent accumulation, where two adjacent cross correlation operations are employed to...
This paper considers the range migration correction problem for realizing the coherent integration of a maneuvering target's energy, involving range walk and range curvature within the coherent integration period. A range migration correction algorithm based on the generalized keystone transform (GKT) is proposed, where two GKT operations and fold factor phase term compensation are employed to remove...
This paper considers the coherent integration detection problem for high speed maneuvering target with a constant jerk, and proposes a new coherent integration detection method involves Keystone transform (KT) and cubic phase function (CPF). Specifically, it employs KT to correct the effect of the range migration. Then, the estimates of the acceleration and jerk with CPF are obtained to compensate...
