It is a challenge to detect or recognize targets with fast complex motion for high range resolution radar
by reason of migration through resolution cells (MTRC) during the observing time.Aiming at solving the problem of MTRC for rotating targets
this paper proposes a new method named Segmental Pseudo Keystone Transform (SPKT)
to correct the MTRC.Observed data is divided into pieces obeying the rules firstly.Each piece of data is processed by the SPKT to realize MTRC correction.And then
data processed is put together to level the HRRP in the whole observing time.Based on which
coherent integration is carried out during the accumulation time.The fast realization is achieved by employing the Discrete Match Fourier Transform (DMFT).Computer simulations demonstrate the validity of this algorithm.
