Novel method of parameter estimation for moving target in millimeter-wave short-range linear FMCW radar

Aiming at the Doppler spectrum aberration and range-velocity coupling phenomena in accelerated moving environment for millimeter-wave short-range linear FMCW radar, a novel method is presented which can estimate the target's acceleration, velocity and range effectively. The method can also compensate the Doppler signal with the estimated acceleration, solve Doppler aberration and range-velocity coupling, and improve the detection performance and parameter estimation precision of the accelerated targets. The method has less computation and has a solid arithmetic.
