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.
