In the Linear FMCW radar

the echo signal of moving target with acceleration has Doppler aberration which will degrade the detection performance and parameter estimation of target.Based on the Polynomial Phase Transform method

the paper first estimates the target's acceleration from the Doppler signal with the polynomial phase transformed

then compensates the Doppler signal with the estimated acceleration

finally

estimates the target's velocity from the compensated Doppler signal.The simulation indicates that the method can improve the detection performance and velocity estimation precision of the accelerated targets.
